Add separate option to omit symbols from heavy contrib

Sometimes it is useful to build contrib with debug symbols for further
debugging.

With everything turned ON (i.e. debug build) I got 3.3GB vs 3.0GB w/o
this patch, 9% bloat, thoughts about this is this OK or not for you, if
not STRIP_DEBUG_SYMBOLS_HEAVY_CONTRIB can be OFF by default (regardless
of build type).

P.S. aws debug symbols adds just 1.7%.
v2: rename STRIP_HEAVY_DEBUG_SYMBOLS
v3: OMIT_HEAVY_DEBUG_SYMBOLS
v4: documentation had been removed

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.
