Billy Laws e323938173 FEXCore: Fix RCL/RCR shift wraparound behaviour
This ends up being cleaner to handle outside of
CalculateFlags_ShiftVariable as constant masking is only needed for
RCL/RCR.

Billy Laws 407e26bfee FEXCore: Use TMP1-4 for values that need preserving across spills
The ARM64EC SRA layout will use x0-3 for x86_64 registers, as such any
arguments passed to C ABI functions need to proxy their arguments
through the temporaries and move as appropriate.

Ryan Houdek 1f7a619c79 OpcodeDispatcher: Fixes syscall rcx/r11 generation
Noticed this while writing #3342.

Fixes #3343

The syscall instruction is defined in the documentation that it will set
RCX to the next instruction's RIP and R11 to be RFLAGS. We entirely
skipped this which I noticed while writing unit tests.

Adds unittests to test both 32-bit and 64-bit behaviour because our
helper shares code with both.

I don't know if anything actually relied on this behaviour but we should
definitely support it.
