Add support for Fast Stream Depends

[AndrianEquestrian]

Inspired by PR 854. A slightly cleaner solution, where FastApi separated from Fast Stream properly. Even though they were together at some point, now Fast Stream - is a separate library after all.

Bug: Falsy Dependency Extraction Fails

The _get_marker_from_parameter function fails to extract falsy but valid dependencies (e.g., False, 0, "", or a falsy _Marker) from Depends wrappers. The if _marker := marker_extractor(marker): line's implicit truthiness check prevents marker from being updated when the extracted dependency is falsy. This leaves the original Depends object, causing the subsequent isinstance(_Marker) check to fail, unlike the previous implementation.

Lines 616 to 620 in b414ef7

	for marker_extractor in MARKER_EXTRACTORS:
	if _marker := marker_extractor(marker):
	marker = _marker
	break
