Core: Threadsafety Synchronization Fixes (Frame Advance / FifoPlayer)
...
Fix Frame Advance and FifoPlayer pause/unpause/stop.
CPU::EnableStepping is not atomic but is called from multiple threads
which races and leaves the system in a random state; also instruction
stepping was unstable, m_StepEvent had an almost random value because
of the dual purpose it served which could cause races where CPU::Run
would SingleStep when it was supposed to be sleeping.
FifoPlayer never FinishStateMove()d which was causing it to deadlock.
Rather than partially reimplementing CPU::Run, just use CPUCoreBase
and then call CPU::Run(). More DRY and less likely to have weird bugs
specific to the player (i.e the previous freezing on pause/stop).
Refactor PowerPC::state into CPU since it manages the state of the
CPU Thread which is controlled by CPU, not PowerPC. This simplifies
the architecture somewhat and eliminates races that can be caused by
calling PowerPC state functions directly instead of using CPU's
(because they bypassed the EnableStepping lock).

Make exceptions consistant across all JITs/Interpeters.
...
They all handled it diffrently, so I've just moved it into Advance()
This fixes Pokemon Box booting in JIT/JITIL which shared a bug where
exceptions set in a scheduled event would be ignored untill the next
slice (upto 20,000 cycles).

Interpreter: don't always set FPSCR.FX on NaNs

FPSCR.FX must only be set if an exception bit changes from 0 to 1.
SetFPException() already handles this correctly.
