std_detect: Add aarch64/linux/LLVM features
Add detection for various aarch64 CPU features already supported by LLVM and Linux. This commit adds feature detection for the following features: - FEAT_CSSC - FEAT_ECV - FEAT_FAMINMAX - FEAT_FLAGM2 - FEAT_FP8 - FEAT_FP8DOT2 - FEAT_FP8DOT4 - FEAT_FP8FMA - FEAT_HBC - FEAT_LSE128 - FEAT_LUT - FEAT_MOPS - FEAT_LRCPC3 - FEAT_SVE_B16B16 - FEAT_SVE2p1 - FEAT_WFxT It also adds feature detection for FEAT_FPMR. It is somewhat of a special case because FPMR only exists as a feature in LLVM 18, it has been removed from the LLVM upstream. On that account the intention is for it to be detectable at runtime through stdarch but not have a corresponding compile-time Rust target feature. Linux features: https://github.com/torvalds/linux/blob/master/arch/arm64/include/uapi/asm/hwcap.h LLVM features: llvm-project/llvm/lib/Target/AArch64/AArch64.td
