This is a holdover from Citra, where the 3DS has both WaitSynchronization1 and WaitSynchronizationN. The switch only has one form of wait synchronizing (literally WaitSynchonization). This allows us to throw out code that doesn't apply at all to the Switch kernel. Because of this unnecessary dichotomy within the wait synchronization utilities, we were also neglecting to properly handle waiting on multiple objects. While we're at it, we can also scrub out any lingering references to WaitSynchronization1/WaitSynchronizationN in comments, and change them to WaitSynchronization (or remove them if the mention no longer applies).
