drm/i915: Add ability for tracking buffer objects per client
In order to show per client memory usage lets add some infrastructure
which enables tracking buffer objects owned by clients.
We add a per client list protected by a new per client lock and to support
delayed destruction (post client exit) we make tracked objects hold
references to the owning client.
Also, object memory region teardown is moved to the existing RCU free
callback to allow safe dereference from the fdinfo RCU read section.
