PPC/s390: [wasm-simd][arm64][liftoff] Implement extended multiply

Port 1215f2a83b6d8a02b29ea69960ea395776383502

Original Commit Message:

    The codegen is the same as on TurboFan, using Smull, Umull, Smull2, and
    Umull2. The rest of the changes are adding skeleton functions to the
    different archs, which bailout for now. Actual codegen will come in
    future patches.
