intel/perf: prep work to enable new perf counters

intel/perf: prep work to enable new perf counters

Those are not part of the OA reports and need some additional
scaffolding. Those counters are only available when doing queries as
we need to emit MI_SRMs to record them.

Equations making use of those counters are not there yet, they will
come in a follow up commit updating a bunch of oa-*.xml files.

v2: Fix typo

v3: Use PERF_CNT_VALUE_MASK (Marcin)
