40cd4df584 CpuCore: Clear exclusive state after doing a run in dynarmic.
This commit corrects an error in which a Core could remain with an
exclusive state after running, leaving space for possible race
conditions between changing cores.

e4c381b885 core/memory: Migrate over Write{8, 16, 32, 64, Block} to the Memory class
The Write functions are used slightly less than the Read functions,
which make these a bit nicer to move over.

The only adjustments we really need to make here are to Dynarmic's
exclusive monitor instance. We need to keep a reference to the currently
active memory instance to perform exclusive read/write operations.

8fc806e88a yuzu: Remove setting for using Unicorn
The JIT is mature enough that this setting can be removed, falling back
to Unicorn only on unsupported architectures. Any missing features from
Unicorn (of which there are extremely few), are mostly
developer-oriented, which most users don't care about.

Features should be coordinated with the JIT, not the interpreter,
anyhow.

447bdac298 yuzu: Remove CPU Jit setting from the UI
A normal user shouldn't change this, as it will slow down the emulation and can lead to bugs or crashes. The renaming is done in order to prevent users from leaving this on without a way to turn it off from the UI.

b117ca5fce kernel/svc: Deglobalize the supervisor call handlers
Adjusts the interface of the wrappers to take a system reference, which
allows accessing a system instance without using the global accessors.

This also allows getting rid of all global accessors within the
supervisor call handling code. While this does make the wrappers
themselves slightly more noisy, this will be further cleaned up in a
follow-up. This eliminates the global system accessors in the current
code while preserving the existing interface.

781ab8407b general: Use deducation guides for std::lock_guard and std::unique_lock
Since C++17, the introduction of deduction guides for locking facilities
means that we no longer need to hardcode the mutex type into the locks
themselves, making it easier to switch mutex types, should it ever be
necessary in the future.

fad20213e6 kernel/scheduler: Pass in system instance in constructor
Avoids directly relying on the global system instance and instead makes
an arbitrary system instance an explicit dependency on construction.

This also allows removing dependencies on some global accessor functions
as well.

bd983414f6 core_timing: Convert core timing into a class
Gets rid of the largest set of mutable global state within the core.
This also paves a way for eliminating usages of GetInstance() on the
System class as a follow-up.

Note that no behavioral changes have been made, and this simply extracts
the functionality into a class. This also has the benefit of making
dependencies on the core timing functionality explicit within the
relevant interfaces.

48d9d66dc5 core_timing: Rename CoreTiming namespace to Core::Timing
Places all of the timing-related functionality under the existing Core
namespace to keep things consistent, rather than having the timing
utilities sitting in its own completely separate namespace.

aeadbfa790 core: Make the exclusive monitor a unique_ptr instead of a shared_ptr
Like the barrier, this is owned entirely by the System and will always
outlive the encompassing state, so shared ownership semantics aren't
necessary here.

c34efbbd60 core: Make CPUBarrier a unique_ptr instead of a shared_ptr
This will always outlive the Cpu instances, since it's destroyed after
we destroy the Cpu instances on shutdown, so there's no need for shared
ownership semantics here.

598e4d2f6c core_cpu: Make arm_interface instances a std::unique_ptr
This is only exposed by reference, so we can just make it a unique
pointer to get rid of the need to also use reference counting for the
pointer.

4a84986bc3 core/core_cpu: Replace exclusive monitor include with forward declaration
We don't need to include this as a dependency within the header. A

d923766042 CPU/Timing: Use an approximated amortized amount of ticks when advancing timing.
We divide the number of ticks to add by the number of cores (4) to obtain a more or less rough estimate of the actual number of ticks added. This assumes that all 4 cores are doing similar work. Previously we were adding ~4 times the number of ticks, thus making the games think that time was going way too fast.

This lets us bypass certain hangs in some games like Breath of the Wild.

We should modify our CoreTiming to support multiple cores (both running in a single thread, and in multiple host threads).

bf45092c61 kernel: Move object class to its own source files
General moving to keep kernel object types separate from the direct

global kernel state in the kernel code.
