feat: Topological sort of dependencies

[runeh]

Sort roots topologically by their dependencies before generating code. Makes sure non-lazy types are written in the correct order.

I'll add a couple of more tests, but apart from that, this should be ready. This should land before releasing 3.0

@cobraz I need this to get released for some other experiments now :)

Hmm. Found a couple of bugs to squash first.

Thank you for this awesome feature!

I can't find any obvious bugs with this. Let me know if you want help with that!

In both of the visitor functions in util, we throw. This crashes when dealing with unknown named types. Should probably just break and continue. But needs a test that triggers it before fixing
