perf completion: Support completion of libpfm4 events
Use `perf list --raw-dump pfm` to support completion of libpfm4 events.
Committer testing:
# grep -m1 'model name' /proc/cpuinfo
model name : AMD Ryzen 9 5950X 16-Core Processor
Before:
Files in the current directory are expanded when <tab>
After:
Only the PFM events are:
# . tools/perf/perf-completion.sh
# perf stat --pfm-events <tab>
Becomes:
# perf stat --pfm-events perf_raw::r0000
As apparently there are no other PFM events for this Ryzen 9 5950X
machine.
