wasm2js: Have instantiate function take standard import object (#5018)

Previously we were assuming asmLibraryArg which is what emscripten
passes as the `env` import object but using this method is more
flexible and should allow wasm2js to work with import that are
not all form a single object.

The slight size increase here is just temporary until emscripten
gets updated.
