feat: Enable compilation on/for arm64 targets

[the-wondersmith]

PR puts the inclusion of xmmintrin.h behind an if defined check to enable compiling daz for/on arm64 targets

I don't think _mm_getcsr x86 intrinsics is supported on Arm64?

you are right. fixed this at https://github.com/hayguen/daz
but finally, on systems without SSE like ARM, the functions do nothing

@hayguen So... (just clarifying) the PR can be closed?

[hayguen]

@the-wondersmith : IMHO yes, in case my pull request #8 would get accepted, yours would get obsoleted. but i fear, there is no reaction from @chainer ?!

in addition, your PR doesn't compile/run on ARM, that is, why i added commit 0d08e77
