This commit adds an optimization to `wasm-bindgen` to directly import and invoke other modules' functions from the wasm module, rather than going through a shim in the imported bindings. This will be an important optimization in the future for the host bindings proposal, but for now it's largely just a proof-of-concept to show that we can do it and is unlikely to bring about many performance benefits. The implementation in this commit is largely refactoring to reorganize a bit how functions are imported, but the implementation happens in `generate_import_function`. With this commit, 71/287 imports in the `tests/wasm/main.rs` suite get hooked up directly to the ES modules, no shims needed!
