Order definitions via a dependency graph

[SebastienGllmt]

Currently, we parse rules as they come doing multiple passes. It would be nice if we instead generated a dependency graph of rules and then parsed rules based on this graph

We'll need to handle cycles for recursive types in some way e.g. plutus_data which references plutus_list which references plutus_data. IIRC how it is now we need to hand edit it due to the const variant (since it contains a single datum which leads to undefined type sizes in rust) by making it a box but it's fine for maps/lists since those are already normally heap allocated.
