In preparation for having these also cover AVX10, use the helper
functions in preference of open-coded cpu_has_avx512* for those features
that AVX10 includes. Introduce a couple further helper functions where
they weren't previously needed.

Note that this way simd_check_avx512f_sha_vl() gains an AVX512F check
(which is likely benign) and simd_check_avx512bw_gf_vl() gains an
AVX512BW check (which was clearly missing).
