perf shell completion: Support completion of metrics/metricgroups
Allow metrics to expand for -M or --metrics options.
Committer testing:
# grep -m1 'model name' /proc/cpuinfo
model name : AMD Ryzen 9 5950X 16-Core Processor
#
Before:
Just expansion of files/directories in the pwd are expanded:
# . tools/perf/perf-completion.sh
# perf stat -M b
block/ build/
# perf stat -M b
After:
# . tools/perf/perf-completion.sh
# perf stat -M
