remove skvx::{rsqrt,rcp}

These don't return reliable portable results, so I don't want to promote
them as good ideas to use.  You can get at least 5 different results
from these across the four main architectures we support, and they've
been the root cause of bugs uncovered only in production on undertested
platforms.

Luckily, unused outside of tests.
