Arm64: Moves some unaligned atomic handling before mutex lock 
These handlers don't do any code backpatching so locking the spinlock
futex isn't necessary. Move them before the lock to make them a bit more
efficient once code buffers get shared.

FEXCore: Disable vixl linking if vixl disasm or simulator is disabled 
This was mostly there, just needed to remove some extraneous headers and
only insert vixl in to the library list if the options were enabled.

OpcodeDispatcher: Remove old bad assumption in INC/DEC 
Somewhere there was an assumption made that INC and DEC supported the
repeat prefix. This isn't actually the case, while the prefix can be
encoded, it is a nop and should only expect to be used for padding.

Adds a unittest to ensure that behaviour is as expected.

LinuxSyscalls: Implements less invasive assertion only EFAULT handlers 
With the previous Copy{To,From}User helpers we need to actually
implement the handlers correctly. We want something that is a bit
lighter so we don't need to implement the faulting path in the syscall
handlers.

Implements a handful of helpers that just check for readable and
writable capability which can be thrown in to an assertion handler that
is zero cost in release mode.

Readable is checked by just attempting to read all bytes.
Writable is checked by attempting to read each byte and writing it back
to the same location.

Uses these helpers in x64/FD.cpp to showcase how they will be used to
detect EFAULT. Tested locally that they work correctly by writing some
small tests for the syscalls that expect EFAULT.
