0d9fb9ca27 kernel: Fix resource release exception on exit 
After rewriting the resource limit, objects releasing reserved resources require a live kernel instance.
This commit fixes exceptions that occur due to the kernel being destroyed before some objects released their resources, allowing for a graceful exit.

e62886ead0 kernel: Unify result codes (#5890) 
* kernel: Unify result codes

Drop the usage of ERR_NAME convention in kernel for ResultName. Removed seperation between svc_results.h & errors.h as we mainly include both most of the time anyways.

* oops

* rename errors to svc_results

a13623c68b kernel: Implement host thread register methods without locking 
Locks on GetCurrentHostThreadID were causing performance issues
according to Visual Studio's profiler. It was consuming twice the time
as arm_interface.Run(). The cost was not in the function itself but in
the lockinig it required.

Reimplement these functions using atomics and static storage instead of
an unordered_map. This is a side effect to avoid locking and using linked
lists for reads.

Replace unordered_map with a linear search.

6bf10ea8cf hle/kernel: Fix data race in GetCurrentHostThreadID 
As reported by tsan, host_thread_ids could be read while
any of the RegisterHostThread variants were called.

To fix this, lock the register mutex when yuzu is running in multicore
mode and GetCurrentHostThreadID is called.

7decda6bc2 core_timing: Make use of uintptr_t to represent user_data 
Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.
