We can make this error code an alias of the resource limit exceeded
error code, allowing us to get rid of the lingering 3DS error code of
the same type.

We can treat this as an alias of TooLarge for documentation purposes.
This also lets us get rid of another lingering 3DS-related error code.

This replaces the lingering 3DS constant with the proper one, and
utilizes it within HandleTable's Create() member function.

Also added some proper error handling.

Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case.
Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock.

TODO:
* Fix svcWaitProcessWideKey
* Fix svcSignalProcessWideKey
* Remove the Mutex class.
