[task] Create AlignWakeUps feature
This feature aligns wake ups at 8ms (finchable) boundary in
ThreadControllerWithMessagePumpImpl when allowed by the next pending
wake up.
Doing this in ThreadControllerWithMessagePumpImpl leaves mock time
untouched such that tasks run at the expected time in tests.
