[meta] Create an Emscripten-based version of the core classes

[trev]

Background

JavaScript engines allow a limited amount of memory optimization, we need to use typed arrays for our data. Doing that with JavaScript will produce an unmaintainable codebase, so we decided to use C++ instead and transpile using Emscripten.

What to change

We need to convert a minimal amount of core classes in order for this to make sense, most operations should stay within Emscripten-generated code.
