The Depends function returns a params.Depends instance, so we need to
check isinstance against params.Depends, not the Depends function itself.

- Fix Python 3.8 compatibility by importing Annotated from typing_extensions
when running on Python < 3.9
- Simplify get_typed_signature to not use get_type_hints which was causing
issues with Pydantic v1 parameter detection (Header, Cookie, Query, etc.)
- Instead, expand globalns with module namespace to help resolve forward
references while keeping the original annotation resolution logic intact

When using `from __future__ import annotations` with `Annotated[SomeClass, Depends()]`
where SomeClass is defined after the function, FastAPI was unable to properly
resolve the forward reference and treated the parameter as a query parameter
instead of a dependency.
This fix adds special handling to partially resolve Annotated string annotations,
extracting metadata (like Depends) even when the inner type cannot be fully resolved.
Fixes#13056
