Correct behavior of thread suspension around Raw monitors

The interaction between raw monitors and thread suspension was
different than some real-world agents expected. Real-world agents rely
on the RawMonitorWait function acting as a suspend point.

Changed the raw-monitor implementation to match this behavior.

Add tests for this behavior and for the behavior of RawMonitorExit
(which does not act as a suspend point).
