drm/xe/oa: Add syncs support to OA config ioctl

Browse source

In addition to stream open, add xe_sync support to the OA config ioctl,
where it is even more useful. This allows e.g. Mesa to replay a workload
repeatedly on the GPU, each time with a different OA configuration, while
precisely controlling (at batch buffer granularity) the workload segment
for which a particular OA configuration is active, without introducing
stalls in the userspace pipeline.

v2: Emit OA config even when config id is same as previous, to ensure
    consistent sync behavior (Jose)
