drm/amdgpu: add interface for editing a foreign process's priority v3
The AMDGPU_SCHED_OP_PROCESS_PRIORITY_OVERRIDE ioctls are used to set
the priority of a different process in the current system.
When a request is dropped, the process's contexts will be
restored to the priority specified at context creation time.
A request can be dropped by setting the override priority to
AMDGPU_CTX_PRIORITY_UNSET.
An fd is used to identify the remote process. This is simpler than
passing a pid number, which is vulnerable to re-use, etc.
This functionality is limited to DRM_MASTER since abuse of this
interface can have a negative impact on the system's performance.
v2: removed unused output structure
v3: change refcounted interface for a regular set operation
