- Merge "Fix pause/resume ordering to preserve metric priority" into androidx-main
- Fix pause/resume ordering to preserve metric priority
Test: MetricsContainerTest#validatePriorityOrder
Bug: 286306579
Bug: 307445225
Relnote: "Fix resumeTiming/runWithTimingDisabled to respect metric
priority order, and significantly reduce impact of lower priority
metric pause/resume on higher priority metric results. For example, if
using cpu perf counters via `cpuEventCounter.enable` instrumentation
argument, timeNs is no longer significantly reduced when pause/resume
occur."
Drastically reduces impact of perf event counters on timeNs measurements
