feat: Add new powerMonitor synchronous API (#17144)

Browse source 
`powerMonitor.querySystemIdleState` and `powerMonitor.querySystemIdleTime` had async backing APIs in chromium (https://chromium-review.googlesource.com/c/chromium/src/+/1379183). However, that has changed in ch73. So, this PR deprecates the old async APIs and adds new sync APIs.
