Yes, I tried keeping them separate, but these functions are also used by
gdbserver, so they have to be in a nat/ header, which makes this a bit
more complicated.

But I recently found out that Windows apparently also provides SVE registers
for ARM64 with these same XState functions [1], so if we plan to support that,
we would probably just move them back here anyways.
