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.

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.

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
regular forward declaration will suffice here.

2e7802ad7d Core/HLE: Make the 'reschedule_pending' flag atomic.
Another thread may write to this variable while the core in question is in the middle of checking for a reschedule request.
