bunnei c10a37e5b6 hle: kernel: physical_core: Clear exclusive state after each run.
- This is closer to pre-multicore behavior, and works a bit better.

bunnei 39d356782e hle: kernel: svc: Remove reschedule on svcBreak.
- This breaks things, and is unnecessary, since emulation will be done at this point.

Lioncash 874be0e3e1 svc: Remove unnecessary [[maybe_unused]] tag
The parameter is used in this function, so this suppression isn't
necessary.

Lioncash da7be67daf ipc_helpers: Remove usage of the global system instance
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

Lioncash fc6db97a09 core: Remove usage of unicorn
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

Lioncash fdd9154069 kernel: Fix build with recent compiler flag changes

Lioncash be1954e04c core: Fix clang build
Recent changes to the build system that made more warnings be flagged as
errors caused building via clang to break.

Fixes #4795

ReinUsesLisp b9a9b83bee 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.

Lioncash 39c8d18feb core/CMakeLists: Make some warnings errors
Makes our error coverage a little more consistent across the board by
applying it to Linux side of things as well. This also makes it more
consistent with the warning settings in other libraries in the project.

This also updates httplib to 0.7.9, as there are several warning
cleanups made that allow us to enable several warnings as errors.

Lioncash ec2a6e5ba8 kernel: Remove all dependencies on the global system instance
With this, the kernel finally doesn't depend directly on the global
system instance anymore.

ReinUsesLisp ccdd84a778 hle/scheduler: Fix data race in is_context_switch_pending
As reported by tsan, SelectThreads could write to
is_context_switch_pending holding a mutex while SwitchToCurrent reads it
without holding any.

It is assumed that the author didn't want an atomic here, so the code is
reordered so that whenever is_context_switch_pending is read inside
SwitchToContext, the mutex is locked.

ReinUsesLisp 36eade7f4c 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.

Lioncash f808258ed9 kernel/scheduler: Mark SchedulerLock constructor as nodiscard
Allows the compiler to warn about cases where the constructor is used
but then immediately discarded, which is a potential cause of
locking/unlocking bugs.
