arm: [MVE intrinsics] factorize several binary_m operations

Factorize m-predicated versions of vabdq, vhaddq, vhsubq, vmaxq,
vminq, vmulhq, vqaddq, vqdmladhq, vqdmladhxq, vqdmlsdhq, vqdmlsdhxq,
vqdmulhq, vqrdmladhq, vqrdmladhxq, vqrdmlsdhq, vqrdmlsdhxq, vqrdmulhq,
vqrshlq, vqshlq, vqsubq, vrhaddq, vrmulhq, vrshlq, vshlq
so that they use the same pattern.
