Subject: [PATCH] perf(napi): enable Wasm 128bit SIMD Extension (#27179)

This was enabled in Rolldown (https://github.com/rolldown/rolldown/pull/4484), but wasn't enabled here.

Technically this is a breaking change as this will make the wasm not run in older browsers, but I think it's fine.

I noticed this because this was pointed out in https://x.com/_pi0_/status/2104617588550705201.
