lib/arm: remove unnecessary NATIVE macros

Since most of the uses of the HAVE_*_NATIVE macros have been removed, and most of them provide no additional value over the original compiler-provided macro like __ARM_FEATURE_CRC32 anyway, there's not much point in having them anymore. Remove them, except for HAVE_NEON_NATIVE and which is still worthwhile to have.
