FEXCore: Splits up atomic enablement checks

Ryan Houdek 9c8438f264 FEXCore: Splits up atomic enablement checks 
PR #3980 is adding a feature to merge loadstores in to paired
loadstores, but it was using the incorrect atomic check to determine if
it can safely merge them or not. It was using the GPR atomic check
instead of the vector atomic check. While this would improve performance
on Apple Silicon with its hardware TSO implementation, it would have had
zero impact on Cortex and Oryon.

Instead split out the three config options to live as a boolean check in
the ContextImpl similar to how we disable "AtomicTSOEmulation". Removing
the various configs in the JIT and CPUID so that it queries from the
same context. This makes it clearer that if you are wanting the current
active configuration for memcpy, vector, or general atomic TSO
emulation, you should query one of those three getters.

This also fixes a weird edge case bug in the arm64 JIT where you could
have TSO emulation disable, but still have vector TSO enabled partially.
Just because half a config wasn't checked in {Load,Store}MemTSO for
vectors. If the global "TSOEnabled" option is disabled then TSO should
always be disabled.

Alyssa will be able to pull this in to #3980 once merged and get the
performance uplift on Cortex and Oryon, since our default configuration
is to have vector and memcpy TSO emulation disabled.

Ryan Houdek ef4c4f6e9b FEXCore: Disable vixl linking if vixl disasm or simulator is disabled

Billy Laws a469047e7a FEXCore: Support cooperative suspend on ARM64EC 
ARM64EC doesn't have an explicit callback for suspend, instead this task
is delegated to the kernel setting a bool at a JIT-defined memory
location, as such the faulting based approach as was done for WOW64
cannot be used.

Ryan Houdek 6ff3c90af3 CodeEmitter: Removes vestigial vixl usage 
- IsImmLogical already existed in our CodeEmitter. We just forgot to

This gets us closer to removing vixl's global initializers from FEXCore.
