[master] RFR: OMWorld: Add LightweightSynchronizer::quick_enter - fix incorrectly setup cache [v2]

[Axel Boldt-Christmas]

> `ObjectSynchronizer::quick_enter` did not setup the BasicLock cache correctly when successful. When x86_32 started calling directly into the VM there are paths which never cleared the cache. Add `LightweightSynchronizer::quick_enter` which correctly clears or sets the cache in all paths.
