This adds the API for FEAT_SHA3. It complements the FEAT_SVE_SHA3 API which is specified in #94425.

Note this is a NEON (AdvSimd) extension. It is not a SVE extension.

@tannergooding : As requested, the API for SHA3. SVE versions of BitwiseRotateLeftBy1AndXor exist in SVE_SHA3 and the other ones exist in SVE2
