Add WebAssembly Support

[sirinath]

With WebAssembly getting a lot of traction is it possible to have 2 back ends. One for JS and another for WA.

Keep in mind that wasm still has no GC, so it might not be a terribly natural fit for a language like Java, which assumes GC. Also consider TeaVM's very experimental wasm support as another way to consider turning your Java into wasm.

We are not planning to have WebAssembly support until it is practical for our use cases; for that at minimal we need GC and better JavaScript interop story to be available in WebAsssembly.

I can work on this

We actually implemented experimental WASM support.
(This is not good for production use, it is currently useful for Chrome/V8 team could have real world data to iterate on WASM GC specification)
