Add "compare" on dataclass fields

Add "compare" on dataclass fields

Added :paramref:`_orm.mapped_column.compare` parameter to relevant ORM
attribute constructs including :func:`_orm.mapped_column`,
:func:`_orm.relationship` etc. to provide for the Python dataclasses
``compare`` parameter on ``field()``, when using the
:ref:`orm_declarative_native_dataclasses` feature. Pull request courtesy
Simon Schiele.

Added an additional case for associationproxy into
test_dc_transforms.py -> test_attribute_options
