Add support for typing.Literal in Mapped
Added support for :pep:`586` ``Literal`` to be used in the
:paramref:`_orm.registry.type_annotation_map` as well as within
:class:`.Mapped` constructs. To use custom types such as these, they must
appear explicitly within the :paramref:`_orm.registry.type_annotation_map`
to be mapped. Pull request courtesy Frederik Aalund.
As part of this change, the support for :class:`.sqltypes.Enum` in the
:paramref:`_orm.registry.type_annotation_map` has been expanded to include
support for ``Literal[]`` types consisting of string values to be used,
in addition to ``enum.Enum`` datatypes. If a ``Literal[]`` datatype
is used within ``Mapped[]`` that is not linked in
:paramref:`_orm.registry.type_annotation_map` to a specific datatype,
a :class:`.sqltypes.Enum` will be used by default.
Fixed issue involving the use of :class:`.sqltypes.Enum` within the
:paramref:`_orm.registry.type_annotation_map` where the
:paramref:`_sqltypes.Enum.native_enum` parameter would not be correctly
copied to the mapped column datatype, if it were overridden
as stated in the documentation to set this parameter to False.

Unify doc typing
### Description
<!-- Describe your changes in detail -->
Fixes #9168
This PR replaces common occurrences of [PEP 585](https://peps.python.org/pep-0585/) style type annotations with annotations compatible with older versions of Python.
I searched for instances of the following supported types from the PEP and replaced with their legacy typing couterparts.
* tuple # typing.Tuple
* list # typing.List
* dict # typing.Dict
* set # typing.Set
* frozenset # typing.FrozenSet
* type # typing.Type
I excluded changelog files from being altered, I think some of these could be changed if necessary but others are likely to require manual checking as the change may target the new typing style specifically.
For any examples that included imports, I tried to ensure that the correct typing imports were included and properly ordered.

support NewType in type_annotation_map
Added support for :pep:`484` ``NewType`` to be used in the
:paramref:`_orm.registry.type_annotation_map` as well as within
:class:`.Mapped` constructs. These types will behave in the same way as
custom subclasses of types right now; they must appear explicitly within
the :paramref:`_orm.registry.type_annotation_map` to be mapped.
Within this change, the lookup between decl_api._resolve_type
and TypeEngine._resolve_for_python_type is streamlined to not
inspect the given type multiple times, instead passing
in from decl_api to TypeEngine the already "flattened" version
of a Generic or NewType type.

apply of_type error message to load.options() as well
Improved the error reporting when linking strategy options from a base
class to another attribute that's off a subclass, where ``of_type()``
should be used. Previously, when :meth:`.Load.options` is used, the message
would lack informative detail that ``of_type()`` should be used, which was
not the case when linking the options directly. The informative detail now
emits even if :meth:`.Load.options` is used.

don't count / gather INSERT bind names inside of a CTE
Fixed regression related to the implementation for the new
"insertmanyvalues" feature where an internal ``TypeError`` would occur in
arrangements where a :func:`_sql.insert` would be referred towards inside
of another :func:`_sql.insert` via a CTE; made additional repairs for this
use case for positional dialects such as asyncpg when using
"insertmanyvalues".
at the core here is a change to positional insertmanyvalues
where we now get exactly the positions for the "manyvalues" within
the larger list, allowing non-"manyvalues" on the left and right
sides at the same time, not assuming anything about how RETURNING
renders etc., since CTEs are in the mix also.
When using the :class:`.MappedAsDataclass` superclass, all classes within
the hierarchy that are subclasses of this class will now be run through the
``@dataclasses.dataclass`` function whether or not they are actually
mapped, so that non-ORM fields declared on non-mapped classes within the
hierarchy will be used when mapped subclasses are turned into dataclasses.
This behavior applies both to intermediary classes mapped with
``__abstract__ = True`` as well as to the user-defined declarative base
itself, assuming :class:`.MappedAsDataclass` is present as a superclass for
these classes.
This allows non-mapped attributes such as ``InitVar`` declarations on
superclasses to be used, without the need to run the
``@dataclasses.dataclass`` decorator explicitly on each non-mapped class.
The new behavior is considered as correct as this is what the :pep:`681`
implementation expects when using a superclass to indicate dataclass
behavior.

derive optional for nullable from interior of pep-593 types
Improved the ruleset used to interpret :pep:`593` ``Annotated`` types when
used with Annotated Declarative mapping, the inner type will be checked for
"Optional" in all cases which will be added to the criteria by which the
column is set as "nullable" or not; if the type within the ``Annotated``

considered nullable if there are no explicit

add __init__ to DeclarativeBase directly
Fixed regression in :class:`.DeclarativeBase` class where the registry's
default constructor would not be applied to the base itself, which is
different from how the previous :func:`_orm.declarative_base` construct
works. This would prevent a mapped class with its own ``__init__()`` method
from calling ``super().__init__()`` in order to access the registry's
default constructor and automatically populate attributes, instead hitting
``object.__init__()`` which would raise a ``TypeError`` on any arguments.
This is a very simple change in code, however explaining it is
very complicated.

mypy plugin fixes
Adjustments made to the mypy plugin to accommodate for some potential
changes being made for issue #236 sqlalchemy2-stubs when using SQLAlchemy
1.4. These changes are being kept in sync within SQLAlchemy 2.0.
The changes are also backwards compatible with older versions of
sqlalchemy2-stubs.
Fixed crash in mypy plugin which could occur on both 1.4 and 2.0 versions
if a decorator for the :func:`_orm.registry.mapped` decorator were used
that was referenced in an expression with more than two components (e.g.
``@Backend.mapper_registry.mapped``). This scenario is now ignored; when
using the plugin, the decorator expression needs to be two components (i.e.
``@reg.mapped``).

pass driver_connection to TypeInfo.fetch()
Fixed regression where psycopg3 changed an API call as of version 3.1.8 to
expect a specific object type that was previously not enforced, breaking
connectivity for the psycopg3 dialect.

dont assume copy_with() on builtins list, dict, etc; improve error msg.
Fixed issue where using an ``Annotated`` type in the
``type_annotation_map`` which itself contained a plain container type (e.g.
``list``, ``dict``) generic type as the target type would produce an
internal error where the ORM were trying to interpret the ``Annotated``
instance.
Added an error message when a :func:`_orm.relationship` is mapped against
an abstract container type, such as ``Mapped[Sequence[B]]``, without
providing the :paramref:`_orm.relationship.container_class` parameter which
is necessary when the type is abstract. Previously the the abstract
container would attempt to be instantiated and fail.

super-fine pass through the metadata tutorial
try to keep the wordiness down here, using sidebars
and topics for non-essential information. Sphinx seems
to read out attrs from under TYPE_CHECKING sections now
so link out the attrs in DeclarativeBase w/ docstrings,
not sure why we didn't think of this earlier. looks great

apply pep-612 to hybrid_method; accept SQLCoreOperations
Fixes to the annotations within the ``sqlalchemy.ext.hybrid`` extension for
more effective typing of user-defined methods. The typing now uses
:pep:`612` features, now supported by recent versions of Mypy, to maintain
argument signatures for :class:`.hybrid_method`. Return values for hybrid
methods are accepted as SQL expressions in contexts such as
:meth:`_sql.Select.where` while still supporting SQL methods.

implement polymorphic_abstract=True feature
Added a new parameter to :class:`_orm.Mapper` called
:paramref:`_orm.Mapper.polymorphic_abstract`. The purpose of this directive
is so that the ORM will not consider the class to be instantiated or loaded
directly, only subclasses. The actual effect is that the
:class:`_orm.Mapper` will prevent direct instantiation of instances
of the class and will expect that the class does not have a distinct
polymorphic identity configured.
In practice, the class that is mapped with
:paramref:`_orm.Mapper.polymorphic_abstract` can be used as the target of a
:func:`_orm.relationship` as well as be used in queries; subclasses must of
course include polymorphic identities in their mappings.
The new parameter is automatically applied to classes that subclass
the :class:`.AbstractConcreteBase` class, as this class is not intended
to be instantiated.
Additionally, updated some areas of the single table inheritance
documentation to include mapped_column(nullable=False) for all
subclass-only columns; the mappings as given didn't work as the
columns were no longer nullable using Annotated Declarative Table
style.
