a25cd4bb4b core: hle: kernel: Update init_slab_heap, use device memory, and add KThreadLocalPage and KPageBuffer.
- Refreshes our slab initialization code to latest known behavior.
- Moves all guest kernel slabs into emulated device memory.
- Adds KThreadLocalPage and KPageBuffer, which we will use for accurate TLS management.

16784e5bb3 dynarmic: Inline exclusive memory accesses
Inlines implementation of exclusive instructions into JITted code,
improving performance of applications relying heavily on these
instructions.

We also fastmem these instructions for additional speed, with
support for appropriate recompilation on fastmem failure.

An unsafe optimization to disable the intercore global_monitor is also
provided, should one wish to rely solely on cmpxchg semantics for
safety.

This allows for better compiler errors, where the compiler will state a

Previously a compiler would warn about the relevant function not being

3a1a3dd0db hle: kernel: KScheduler: Fix deadlock with core waiting for a thread lock that has migrated.
- Previously, it was possible for a thread migration to occur from core A to core B.
- Next, core B waits on a guest lock that must be released by a thread queued for core A.
- Meanwhile, core A is still waiting on the core B's current thread lock - resulting in a deadlock.
- Fix this by try-locking the thread lock.
- Fixes softlocks in FF8 and Pokemon Legends Arceus.

- PR #7699 attempted to fix CreateServiceThread and ReleaseServiceThread to be thread safe, but inadvertently introduced a possible dead-lock.
- With this PR, we use a worker thread to manage the service thread list, allowing it only to be accessed by a single thread, and guaranteeing threads will not destroy themselves.
- Fixes a rare crash in Pokemon Sword/Shield, I've now run this game for ~12 hours non-stop and am quite confident this is a good solution for this issue.
