The API is implemented in javascript, and generates C functions that can be called from godot. This allows much cleaner code replacing all `EM_ASM` calls in our C++ code with plain C function calls. This also gets rid of few hacks and comes with few optimizations (e.g. custom cursor shapes should be much faster now).
