Kernel: Reduce LOCK_DEBUG ifdefs by utilizing Kernel::LockLocation

Browse source 
The LOCK_DEBUG conditional code is pretty ugly for a feature that we
only use rarely. We can remove a significant amount of this code by
utilizing a zero sized fake type when not building in LOCK_DEBUG mode.

This lets us keep the same API, but just let the compiler optimize it
away when don't actually care about the location the caller came from.
