Revert "[wasm-simd] Fix extract lane unsigned extend"

This reverts commit dfdef885474efbce7fa623b02d1df4a984fede86.

Reason for revert: https://ci.chromium.org/p/v8/builders/ci/V8%20Blink%20Mac/2718?

Original change's description:
> [wasm-simd] Fix extract lane unsigned extend
> 
> The interpreter is missing a static cast when extracting lanes smaller
> than int32_t and doing an unsigned extend. The array in Simd128 is
> signed, so a direct cast to uint32_t will be a signed extension. The fix
> is to, in the unsigned case, cast to unsigned (of the appropriate size)
> first, then cast to uint32_t.
