Add support for WebAssembly ESM proposal (AKA WebPack `experiments.asyncWebAssembly`, vite-plugin-wasm, etc)

Feature suggestion

This is a mode that is interoperable with bundlers, and is also supported in node under --experimental-wasm-modules, rather than relying on the bundler packaging the WASM as an asset and knowing to ignore the node specific code.

Excellent idea, but it might take some time for someone to get to this.
