[3.9] [3.10] bpo-46576: bpo-46524: Disable compiler optimization within test_peg_generator. (GH-31015) (GH-31089) (GH-31093)

Disable compiler optimization within test_peg_generator.

This speed up test_peg_generator by always disabling compiler
optimizations by using -O0 or equivalent when the test is building its
own C extensions.

A build not using --with-pydebug in order to speed up test execution
winds up with this test taking a very long time as it would do
repeated compilation of parser C code using the same optimization
flags as CPython was built with.

This speeds the test up 6-8x on gps-raspbian.

Also incorporate's GH-31017's win32 conditional and flags.

[3.9] bpo-45703: Invalidate _NamespacePath cache on importlib.invalidate_cache (GH-29384) (GH-30922) (GH-31076)

Consider the following directory structure:

    .
    └── PATH1
        └── namespace
            └── sub1
                └── __init__.py

And both PATH1 and PATH2 in sys path:

    $ PYTHONPATH=PATH1:PATH2 python3.11
    >>> import namespace
    >>> import namespace.sub1
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> ...

While this interpreter still runs, PATH2/namespace/sub2 is created:

    .
    ├── PATH1
    │   └── namespace
    │       └── sub1
    │           └── __init__.py
    └── PATH2
        └── namespace
            └── sub2
                └── __init__.py

The newly created module cannot be imported:

    >>> ...
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> import namespace.sub2
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ModuleNotFoundError: No module named 'namespace.sub2'

Calling importlib.invalidate_caches() now newly allows to import it:

    >>> import importlib
    >>> importlib.invalidate_caches()
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace'])
    >>> import namespace.sub2
    >>> namespace.__path__
    _NamespacePath(['.../PATH1/namespace', '.../PATH2/namespace'])

This was not previously possible.

Fix a Python crash in test_lib2to3 when using Python built in debug
mode: limit the recursion limit.

The test_all_project_files() test of test_lib2to3 now uses the
test.support.infinite_recursion() context manager when processing the
infinite_recursion.py file to prevent a crash when Python is built in
debug mode.

The two test_all_project_files() tests now use subTest() and log the
refactored/parsed filename (if test_lib2to3 is run in verbose mode).

* Update Lib/lib2to3/tests/data/infinite_recursion.py

- there is no alternative solution available from the Python C API
  due to how the new parser works (rewritten in 3.9)
- the only supported way is to manually import the codeop module from C
  and use its API as IDLE does, and accept its own complications

it is desirable to remove this Q&A from the official FAQ..

[3.9] bpo-45680: Clarify documentation on ``GenericAlias`` objects (GH-29335) (GH-30689)

The documentation on ``GenericAlias`` objects implies at multiple points that
only container classes can define ``__class_getitem__``. This is misleading.
This PR proposes a rewrite of the documentation to clarify that non-container
classes can define ``__class_getitem__``, and to clarify what it means when a
non-container class is parameterized.

See also: initial discussion of issues with this piece of documentation in
GH-29308, and previous BPO issue [42280](https://bugs.python.org/issue42280).

Also improved references in glossary and typing docs. Fixed some links.

bpo-13886: Skip PTY non-ASCII tests if readline is loaded (GH-30631) (GH-30635)

Skip test_builtin PTY tests on non-ASCII characters if the readline
module is loaded. The readline module changes input() behavior, but
test_builtin is not intented to test the readline module.

When the readline module is loaded, PyOS_Readline() uses the readline
implementation. In some cases, the Python readline callback
rlhandler() is called by readline with a string without non-ASCII
characters.
