This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
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
