[Fix] re_cache: Respect disable_hyperscan option in loading functions

Add checks for disable_hyperscan at the start of hyperscan loading
functions to prevent database loading when the option is set.

Previously, hyperscan databases would still be loaded even with
disable_hyperscan = true, causing unnecessary I/O and memory usage.
