Reland: Don't use hwasan for non-bionic arm64 targets
Don't use hwasan for non-bionic arm64 targets, including
arm64-linux-musl and arm64 darwin.
This relands I67c07f26f25a9f9807ee21ee79c113ea11f65473 which was
accidentally reverted in I47a9322929baff2492c6e8db989ece01fcbeb133.
Bug: 236052820
Test: build arm64 musl sysroot
