Replace hyperscan by vectorscan 
This commit migrates ClickHouse to Vectorscan. The first 10 min of
[0] explain the reasons for it.

(*) Addresses (but does not resolve) #38046

(*) Config parameter names (e.g. "max_hyperscan_regexp_length") are
    preserved for compatibility. Likewise, error codes (e.g.
    "ErrorCodes::HYPERSCAN_CANNOT_SCAN_TEXT") and function/class names (e.g.
    "HyperscanDeleter") are preserved as vectorscan aims to be a drop-in
    replacement.
