[sim] Change StepTiming to wait for notifiers (#2603)

Old behavior is available via StepTimingAsync.

This makes it significantly easier to use simulation timing with notifiers.

Also update tests to use simulation framework.  This also speeds up the
timing-dependent tests by using simulation timing.  ResourceLock is used
in the Java tests to prevent parallel execution.

While we're here, tweak HAL Notifier implementation:
- Use wait_for instead of wait_until in WaitForNotifierAlarm
- Check for triggerTime = UINT64_MAX in UpdateNotifierAlarm
