1b8ed3a76d 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.

b3f8d2491d hle: kernel: KThread: Ensure host (dummy) threads block on locking. 
- But do not enter the priority queue, as otherwise they will be scheduled.
- Allows dummy threads to use guest synchronization primitives.

01852ee857 hle: remove no-op code 
Found by static analysis with PVS-Studio. Nobody seems to really know what was it doing there.

b12695ddc4 core: hle: kernel: Implement thread pinning. 
- We largely had the mechanics in place for thread pinning, this change hooks these up.
- Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_thread_pinning.cpp.

c9f9e77be3 core/arm_interface: Call SVC after end of dynarmic block. 
So we can modify all of dynarmic states within SVC without ExceptionalExit.

Especially as the ExceptionalExit hack is dropped on upstream dynarmic.

eeae5217ba core: Make variable shadowing a compile-time error 
Now that we have most of core free of shadowing, we can enable the
warning as an error to catch anything that may be remaining and also
eliminate this class of logic bug entirely.

3322f10f84 core: Switch to unique_ptr for usage of Common::Fiber. 
- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.
