Richard Cooper bc4322ede9 configs: Add --pmu-{dump,reset}-stats-on to Arm baremetal.py. ...

Add `--pmu-dump-stats-on <event>` and `--pmu-reset-stats-on <event>`
options to the Arm `baremetal.py` config to optionally dump and/or
reset stats on various PMU events.

These options allow the user to specify which PMU events should cause
the dumping or resetting of gem5 stats. The available `<event>`s are
PMU `enable`, `disable`, `reset`, and `interrupt`. Both these CLI
options may be specified multiple times to enable more than one event
to cause a stats dump/reset if desired. Stats are dumped before they
are reset.

These options are useful for sampled simulation workloads (e.g.
SimPoints) which are controlled by the PMU.
