On initializing the framebuffer, call drm_any_plane_has_format to do a
check if the modifier is supported. drm_any_plane_has_format calls
dm_plane_format_mod_supported which is extended to validate that the
modifier is on the list of the plane's supported modifiers.

The bug was caught using igt-gpu-tools test: kms_addfb_basic.addfb25-bad-modifier

test, and running a YT video.

Now that we actually expose the right number of planes we get
problems with modifier aware libva if we use an unsupported modifier.

So this ensures that we as much as possible use a modifier that
radeonsi can actually render to without going to extreme difficulty
to synchronize an extra DCC metadata plane with implicit sync.

Looking into the opaque metadata isn't ideal but this converts to
something mainly for the purpose of the userspace driver and falls
back properly if it isn't what we expect.

If we use DCC modifiers this can increase the number of planes from
the initial 1 plane with metadata, so that we get a valid modifier
from getfb2.

Since the code didn't update the format_info getfb2 would only ever
return 1 plane with a modifier for which userspace expects > 1.

This moves the format lookup to amdgpu_display.c so we do not have
issues when DC is not compiled.

Also do the proper validation which was missed.

Besides the missing validation, not storing the objects in the
framebuffer led to wrong results in the getfb2 ioctl.

Note that this should really have been done for multi-plane
formats like NV12 already before modifiers landed.
