AArch64: Add support for MOPS memcpy/memmove/memset
Add support for MOPS in cpu_features and INIT_ARCH. Add ifuncs using MOPS for memcpy, memmove and memset (use .inst for now so it works with all binutils versions without needing complex configure and conditional compilation). Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com> (cherry picked from commit 2bd00179885928fd95fcabfafc50e7b5c6e660d2)
