Subject: [PATCH] gh-127897: fix HACL* build on macOS/Catalina (GH-127932)

gh-127897: Update HACL* module from upstream sources to get:

- Lib_Memzero0.c: don't use memset_s() on macOS <10.9
- Use _mm_malloc() for KRML_ALIGNED_MALLOC on macOS <10.15
- Add LEGACY_MACOS macros, use _mm_free() for KRML_ALIGNED_FREE on macOS <10.15
