2624ac7ae8 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.

63a3b54c1f kernel: Resolve sign conversion warnings 
Uncovered a bug within Thread's SetCoreAndAffinityMask() where an
unsigned variable (ideal_core) was being compared against "< 0", which
would always be a false condition.

We can also get rid of an unused function (GetNextProcessorId) which contained a sign
mismatch warning.

cfb327a85b kernel/thread: Migrate WaitCurrentThread_Sleep into the Thread interface 
Rather than make a global accessor for this sort of thing. We can make
it a part of the thread interface itself. This allows getting rid of a
hidden global accessor in the kernel code.

38dd80f70f 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.

1c3371c921 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.

1d2de5c4b5 core_timing: Rename CoreTiming namespace to Core::Timing

namespace to keep things consistent, rather than having the timing
utilities sitting in its own completely separate namespace.
