drm/amdgpu: add UAPI to query GFX shadow sizes
Add UAPI to query the GFX shadow buffer requirements
for preemption on GFX11. UMDs need to specify the shadow
areas for preemption.
v2: move into existing asic info query
drop GDS as its use is determined by the UMD (Marek)
v3: Update comments to note that alignment is base
virtual alignment (Alex)
