[Intel-xe] [PATCH 13/17] drm/xe/oa: Multiplex PERF ops through a single PERF ioctl

Since we are already mulitplexing multiple perf counter stream types
through the PERF layer, it seems odd to retain separate ioctls for perf
op's (add/remove config). In fact it seems logical to also multiplex these
ops through a single PERF ioctl. This also affords greater flexibility to
add stream specific ops if needed for different perf stream types.
