egl/wayland-drm: Only announce formats via wl_drm which the driver supports.
Check if a pixel format is supported by the Wayland servers gpu driver
before exposing it to the client via wl_drm, so we avoid reporting formats
to the client which the server gpu can't handle.
Restrict this reporting to the new color depth 30 formats for now, as the
ARGB/XRGB8888 and RGB565 formats are probably supported by every gpu under
the sun.
Atm. this is mostly useful to allow proper PRIME renderoffload for depth
30 formats on the typical Intel iGPU + NVidia dGPU "NVidia Optimus" laptop
combo.
Tested on Intel, AMD, NVidia with single-gpu setup and on a Intel + NVidia
Optimus setup.
