Report CPU state via Compute Pressure API#3230

Conversation
Add a CPU_PRESSURE_STATE SdkMetric (=113) and a ComputePressureMonitor that wraps the browser PressureObserver. The monitor returns the raw pressure state string; StatsCollector owns the wire encoding (nominal=0, fair=1, serious=2, critical=3) and appends the latest sample to each global metric frame. The class is internal — added to barrelize.js ignoredTypes alongside StatsCollector.

Issue #: N/A
Description of changes:
Add a CPU_PRESSURE_STATE SdkMetric (=113) and a ComputePressureMonitor that wraps the browser PressureObserver. StatsCollector owns the monitor's lifetime and appends the latest sample (nominal=0, fair=1, serious=2, critical=3) to each global metric frame. The class is internal — added to barrelize.js ignoredTypes alongside StatsCollector.
Testing:
On my macos can emit both 0 and 1
Can these tested using a demo application? Please provide reproducible step-by-step instructions.
