drm/amdgpu: add INFO ioctl support for querying video caps (v4)
We currently hardcode these in mesa, but querying them from
the kernel makes more sense since there may be board specific
limitations that the kernel driver is better suited to
determining.
Userpace patches that use this interface:

v2: reorder the codecs to better align with mesa
v3: add max_pixels_per_frame to handle the portrait case, squash in
memory leak fix
v4: drop extra break
