**Describe the unexpected behaviour**
VectorScan is cross-platform, yet ClickHouse enables it only for x86

**Additional context**
- #38171 replaced hyperscan by vectorscan which is a cross-platform fork of hyperscan. Due to wrong results on ARM (see the PR), we currently compile vectorscan only for x86. Need to check if a new version resolves the problem or continue investigation.
- Once done, we can remove the non-vectorscan fallback code in file "Functions/MultiMatchAnyImpl.h"
