aarch64: Use memcpy_simd as the default memcpy
Since __memcpy_simd is the fastest memcpy on almost all cores, replace the generic memcpy with it. If SVE is available, a SVE memcpy will be used by default (including for Neoverse N2). (cherry picked from commit e6f3fe362f1aab78b1448d69ecdbd9e3872636d3)
