Core: Remove MemoryWatcher

MemoryWatcher only works on Linux and affects emulation determinism due
to scheduling additional events, which causes NetPlay to desync.
Considering that this interface is a rather specialized use case, the
communication with it is kinda crappy *and* it's affecting emulation, I
think it's best to just axe it and come up with a better implementation
of the functionality.
