drm/amdgpu: re-work VM syncing

Browse Source 
Rework how VM operations synchronize to submissions. Provide an
amdgpu_sync container to the backends instead of an reservation
object and fill in the amdgpu_sync object in the higher layers
of the code.

No intended functional change, just prepares for upcomming changes.
