perf/x86: Support Retire Latency
Retire Latency reports the number of elapsed core clocks between the
retirement of the instruction indicated by the Instruction Pointer field
of the PEBS record and the retirement of the prior instruction. It's
enumerated by the IA32_PERF_CAPABILITIES.PEBS_TIMING_INFO[17].
Add flag PMU_FL_RETIRE_LATENCY to indicate the availability of the
feature.
The Retire Latency is not supported by the fixed counter 0 on p-core of
MTL.
