wasm2js2 import fixes (#2031)

* Don't assume function types exist in legalize-js-interface.
* Properly handle (ignore) imports in RemoveNonJSOps - do not try to recurse into them.
* Run legalize-js-interface and remove-unused-module-elements in wasm2js, the first is necessary, the last is nice to have.
