vkformat: check the requested usage against format features correctly (and other fixes)

This does mean that if the primary format fails validation, then we need to fallback to the secondary vulkan format/s.

Fixes: #2957 (closed)

Other fixes:

commit c6e318de

vkformat: assume that unknown rgb transfer is sRGB

commit 22ce6f9d

vkformat: also check configured usage flags

This does also mean that if the primary format fails this check, we need
to try the secondary format before returning an error

commit a07056d7

vkformat: invert srgb and multiplane && planes > 1 checks

The primary format for RGB includes sRGB transfer but was not actually
being used.

The !(no_multiplane && planes > 1) check for YUV resulted in those
formats never being used.

commit ec9ff76d

vkformat: FORMAT_FEATURE_COLOR_ATTACHMENT also includes INPUT_ATTACHMENT

commit f01dbc5a

vkformat: reorder RGBA formats before RGBx formats

Fixes gst_vulkan_format_to_video_format to use the RGBA formats instead
of RGBx formats.

Fixes vulkansink exposing a RGBx/BGRx format instead of the more
relevant RGBA/BGRA formats
