[libcamera-devel] [PATCH v3 5/7] v4l2: v4l2_camera_proxy: Report the proper format name in enum_fmt

Now that libcamera has the V4L2 format names, retrive and report those
names in ENUM_FMT. While at it, refactor the code slightly with
PixelFormatInfo.

This fixes the test failures on v4l2-compliance with the v4l2
compatilibity layer that were observed in version v4l2-compliance
version 1.21.0-4838.
