cmake: revert commit 5d1bbd9 and change sse4.2 test

clang doesn't support -mcrc32 until version 14.0, therefore drop -mcrc32
use in sse 4.2 test, and change it to check _mm_cmpgt_epi64() instead of
_mm_crc32_u32(). without this, sse4.2 check was failing with clang <= 13

Fixes #12223

(cherry picked from commit 8756536)
