Wasm plugin to support latest ESM Integration & Source Phase Imports

[guybedford]

• Rollup Plugin Name: wasm
• Rollup Plugin Version:

Feature Use Case

The WebAssembly ESM Integration proposal recently reached phase 3 in the WebAssembly process. It would be great if Rollup's Wasm plugin could align with this latest proposal to unify the runtime and build-time behaviours for Wasm imports.

Feature Proposal

See https://github.com/WebAssembly/esm-integration.

I may be able to assist with review or some implementation work here.
