drm/i915/perf: Configure OAR for specific context
Gen12 supports saving/restoring render counters per context. Apply OAR
configuration only for the context that is passed in to perf.
v2:
- Fix OACTXCONTROL value to only stop/resume counters.
- Remove gen12_update_reg_state_unlocked as power state is already
applied by the caller.
v3: (Lionel)
- Move register initialization into the array
- Assume a valid oa_config in enable_metric_set
