enh(query)[TD-32652]: enable AVX implementation with CPU dispatching
...
Extract AVX implementation of specific functions into separate files.
The CPU dispatching mechanism will now check the machine's instruction
set at runtime to determine whether to use the AVX implementation or
fallback to the naive version.
This enhancement improves performance on most machines while ensuring
compatibility with older hardwares.
