fix optionalized forms for dict[]

Fixed a suite of issues involving :class:`.Mapped` use with dictionary
types, such as ``Mapped[dict[str, str] | None]``, would not be correctly
interpreted in Declarative ORM mappings. Support to correctly
"de-optionalize" this type including for lookup in type_annotation_map has
been fixed.

Fixes: #8777
