perfetto: Arm mm event trace config
If persist.perfetto.mm_events.enabled=true periodically
arm mm_event trace config.
The config is only armed if perfotto traced daemon is active.
If arming the config fails, the arm interval is increased
by a backoff factor before retrying.
If 10 failures occur in succession, abort trying to arm
the config.
If an alternate vendor trace config is present at
/vendor/etc/mm_events.cfg it will be armed instead of the default.
The mm_events props are configurable from vendor init.
Bug: 183037386
Test: Manual.
- Set prop enabled,
- Synthesize memory pressure
- Verify perfetto trace data captured in bugreport
