drm/amdgpu: add gfx shadow CS IOCTL support

Browse source

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)
