drm/amdgpu: add gfx shadow CS IOCTL support
Add support for submitting the shadow update packet
when submitting an IB. Needed for MCBP on GFX11.
v2: update API for CSA (Alex)
v3: fix ordering; SET_Q_PREEMPTION_MODE most come before COND_EXEC
Add missing check for AMDGPU_CHUNK_ID_CP_GFX_SHADOW in
amdgpu_cs_pass1()
Only initialize shadow on first use
(Alex)
v4: Pass parameters rather than job to new ring callback (Alex)
v5: squash in change to call SET_Q_PREEMPTION_MODE/COND_EXEC
before RELEASE_MEM to complete the UMDs use of the shadow (Alex)
