Add support for SSE 4.2

Only something to worry about once our performance is good enough for newer AAA titles.

Apparently Doom Eternal uses the CRC instruction specifically. The string compare ops likely won't map very well to anything in AArch64...

Control Ultimate Edition also relies on SSE 4.2

Horizon Zero Dawn uses CRC32 at the very least.

CRC32 implemented with #1541 which gets Horizon Zero dawn running.

@lioncash I think this is done at this point?

It's not, the string comparison ops aren't implemented.

Interestingly, Control checks for SSE 4.2 via CPUID, but we can't even test force enabling it since utility libraries will use SSE4.2 string instructions if exposed.

Control early bails out if CPUID doesn't claim to be available.
