Using hwcaps instead of simde dispatcher scripts?

Hi Michael,

I recently came across Christian's blog[1] (thanks for this!) where they
use hwcaps[2] to select the appropriate cpu capabilities for ggml package[3].

This is similar to what we do when we add simde patches to a package and
build for all ISAs starting from baseline SSE2 until AVX2 (or even AVX512), and
we end up writing a home-grown script like this [4] to select appropriate cpu capabilities.

Do you think we can get rid of these scripts going forward and instead use hwcaps?
