[lworld] RFR: 8370509: [lworld] EnableValhalla is not needed for sync [v2]

[Coleen Phillimore]

> I took out EnableValhalla as a conditional test in the ObjectSynchronizer code.  If the inline type bit is set in the markWord or the klass is InlineKlass, we can't synchronize on the object.
> I added a test but it was sort of a duplicate of all runtime/valhalla/inlinetypes/MonitorEnterTest.java and duplicates all tests that do locking so I didn't add a test.
> Testing with tier1-4, still in progress.
