Denoise hermetric surfaceflinger perf tests

Remove overheard by disabling features during the test including:
- perfetto tracing
- region sampling by hiding navbar
- transaction tracing

Reduce variations between each frame by
- forcing max frame rate (avoids any frame misses)
- consuming transform hint (avoids gpu comp)
- starting simpleperf after test setup to move test activity
launch outside of measurement window
