This relands commit 7c32fa05df.
Some test cases need to be updated, since we will bail out to TurboFan
where previously Liftoff was happy to run, when SIMD is not supported.
Original change's description:
> [wasm-simd][liftoff] Check CpuFeatures for SIMD support
>
> If Wasm simd128 is not supported on this particular hardware, we bail
> out to TurboFan.
