Given that the standalone target for dart2wasm is feature-complete now, it makes sense to include it in released SDKs. This adds the platform and outline files to built SDKs and exposes the `--standalone` flag in `dart compile wasm`. It also documents the standalone target in `pkg/dart2wasm/doc`, which should be helpful as a starting point to use these compiled modules.
