Unity il2cpp type_info_definition_table regression

Nobody has claimed this yet.

# Issue

There has been a couple of reports that the update to the `type_info_definition_table` address sigscan behaviour has regressed and no longer works in certain cases.

https://github.com/LiveSplit/asr/blob/master/src/game_engine/unity/il2cpp/mod.rs#L63-L89

## Known Games affected
- Sea of Stars (2021.3 LTS)

## Other games with invalid definitions (old doesnt fix)
- GRIME II (unity 6)
---

Making this issue as a reminder to work on a reproduction case and potentially some fallback behaviour using the old (potentially slower?) method if an address cannot be resolved using the new method.

I'm assuming the new method was introduced to solve a specific case, would be curious as to what game that was @Jujstme

It could be a matter of testing more games with the newer method to resolve the issue.

Start by reading src/game_engine/unity/il2cpp/mod.rs lines 63-89 and reproduce the type_info_definition_table address sigscan behavior with Sea of Stars or GRIME II. Compare the newer method with the old method when definitions cannot be resolved; done means the affected cases work with an agreed fallback or the regression is otherwise resolved.
