Summary

• Add SVE2 implementation and dispatcher/test coverage for SimdDetectionLbpDetect32fi.
• Document the new SVE2 optimization in release 7.2.163 notes.

Testing

• Built AArch64 SVE2 configuration with explicit aarch64-linux-gnu-g++/gcc compilers.
• Ran focused DetectionLbpDetect32fi test under qemu-aarch64 with QEMU_CPU=max; the test framework reported SIMD: NEON SVE(512) SVE2 and finished successfully.
• Built native x86_64 Release configuration with g++ and ran the same focused test successfully.
