drm/amdgpu: add get_gfx_shadow_info callback for gfx11
Used to get the size and alignment requirements for
the gfx shadow buffer for preemption.
v2: use FW version check to determine whether to
return a valid size here
return an error if not supported (Alex)
v3: drop GDS (Alex)
v4: make amdgpu_gfx_shadow_info mandatory (Alex)
