Updated the uniffi-bindgen-gecko-js code to use two things I've been experimenting with: * Use the IR pipeline code to generate the structs used to render the templates. * A new test fixture for bindings generators. This one targets bindings generators specifically, it doesn't try test the scaffolding code and it's not based on real-world example code. I originally thought it would be a single crate, but I ended up needed 2 in order to test external types.
