WebAssembly (WASM, WASI) Support

### Is your feature request related to a problem or challenge?

Hello, is there any plan to support WebAssembly, especially the targets below?

- wasm32-wasip2
- wasm32-wasip3 (in progress)

### Describe the solution you'd like

_No response_

### Willingness to contribute

I can contribute to this feature independently

Start by reviewing the repository's existing target configuration and build/test entry points for WebAssembly support. Define what successful support means for wasm32-wasip2 and the in-progress wasm32-wasip3 target, then verify the relevant build and test workflows for both targets.
