fixes for AVX detection (#17915)
Summary:
Our AVX2 routines use functions such as _mm256_extract_epi64
that do not exist on 32 bit systems even when they have AVX2.
This disables AVX2 when _mm256_extract_epi64 does not exist.
This fixes the "local" part of #17901 (except disabling FBGEMM),
but there also is sleef to be updated and NNPACK to be fixed,
see the bug report for further discussion.
