[Intel-gfx] [CI 7/9] drm/i915/perf: Allow dynamic reconfiguration of the OA stream

Introduce a new perf_ioctl command to change the OA configuration of the active stream. This allows the OA stream to be reconfigured between batch buffers, giving greater flexibility in sampling. We inject a request into the OA context to reconfigure the stream asynchronously on the GPU in between
