[KBM] Refactor KBM's thread safety logic to avoid mutex re-entrancy bugs and improve performance (#6803)

Browse Source 
* Unlock mutex before ResetModifierForLowerLevelKeyHandlers method to avoid crash if two instances of KBM are running

* Added alias for Shortcut DWORD variant to clean up code

* Removed mutex usage in single key remap method and added GetSingleKeyRemap

* Added more alias

* Moved to boolean disable remapping

* Added missing ! in condition

* Remove lock statement from bad auto-merge
