Inline js support

[hanabi1224]

It looks like the plugin cannot properly bundle inlinejs, is there plan to support that?

Add below code to example/my-crate/src/lib.rs, then the build will fail

#[wasm_bindgen(inline_js = "export function alert2(msg) { alert(msg) }")]
extern "C" {
    fn alert2(s: &str);
}

#[wasm_bindgen]
pub fn greet2(name: &str) {
    alert2(&format!("Hello from js via rs,{}!", name));
}
