vectorscan: Update to version 5.4.12

- Update from version 5.4.11 to 5.4.12
- Update of rootfile
- Removal of patch for sse4.2 as changes now part of source tarball
- Changelog
    5.4.12
	Multiple changes since last release, this will be the last 100% ABI and API
	 compatible with Hyperscan release.
	Next versions will include major refactors and API extensions, it will be
	 mostly backwards compatible however.
	Without particular order, platform support is now:
		* Linux (x86, Arm, Power)
		* FreeBSD 14 (x86, Arm, Power)
		* MacOS 14+ (x86, Arm)
	In total more than 200 configurations in the CI are tested for every PR.
	Other features:
		- Fat Runtime supported for Arm as well (ASIMD/SVE/SVE2).
		- Initial implementations for Arm SVE/SVE2 algorithms added, thanks to
		  Yoan Picchi from Arm.
		- SIMDe support added, used as an alternative backend for existing
		  platforms, but mostly interesting for allowing Vectorscan to build
		  in new platforms without a supported SIMD engine.
		- Various speedups and optimizations.
		- Cppcheck and clang-tidy fixes throughout the code, both have been
		  added to CI for multiple configurations, but only cppcheck triggers
		  a build failure for now.
	Various bugfixes, most important listed:
		- Speed up truffle with 256b TBL instructions (#290)
		- Fix Clang Tidy warnings (#295)
		- Clang 17+ is more restrictive on rebind<T> on MacOS/Boost, remove
		  warning (#332)
		- partial_load_u64 will fail if buf == NULL/c_len == 0 (#331)
		- Bugfix/fix avx512vbmi regressions (#335)
		- fix missing hs_version.h header (closes #198)
		- hs_valid_platform: Fix check for SSE4.2 (#310)
		- Fixed out of bounds read in AVX512VBMI version of
		  fdr_exec_fat_teddy … (#333)
		- Fix noodle SVE2 off by one bug (#313)
		- Make vectorscan accept \0 starting pattern (#312)
		- Fix 5.4.11's config step regression (#327)
		- Fix double shufti's vector end false positive (#325)
