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.
Fixes: #9175
