Andreas Kling 03cc45e5a2 Kernel: Use RefPtr instead of LockRefPtr for File and subclasses
This was mostly straightforward, as all the storage locations are
guarded by some related mutex.

The use of old-school associated mutexes instead of MutexProtected
is unfortunate, but the process to modernize such code is ongoing.
