drm-uapi: extend interface for copy timestamp results CPU job

Browse Source 
Extend the UAPI to support the copy timestamp results user extension for the
CPU job. This user extension will allow the creation of a CPU job that
copies the results of a timestamp query to a BO with the possibility to
indicate the timestamp availability with a availability bit.
