Summary

This PR adds support for the new abi format. The ABI now contains concreteTypes and metadataTypes. A concrete type can be either a built-in type (e.g. u8) or it can be a specific instance of a metadata type. Functions, configurables, logged types, message types - they all now reference only concrete types.

The way I've gone about implementing this in the abi-coder is that I created a ResolvableType for each metadata type, which are then used to get ResolvedTypes for every specific concrete type usage in function inputs, outputs, configurables, etc. This ResolvedType contains all the information necessary to use in coders the same way ResolvedAbiType previously did.

The benefit of this approach is that I could reuse the same concept of ResolvableType and ResolvedType in abi-typegen. Because typegen already interpreted the ABI in such a way previously (this is where I got the inspiration from), it was relatively easy to plug the new solution in.

Once abi-coder and abi-typegen become one package in #2346, the code duplication will cease to exist.

I couldn't go with reusing the old ResolvedAbiType approach in abi-typegen because it approached the ABI in a fundamentally different way. Instead of creating all types and then plugging in specific (concrete) implementations of those types, it would create a tree just for the specific type implementation it was given, which isn't the proper approach for typegen which first lists all the types (generic and non-generic) and then references them in function inputs, outputs, and configurables.

Breaking Changes

TBD once reviews are done.

Closing this PR in favor of #2856 and we'll later use it when we approach the abi (typegen + coder) holistically in a rewrite.
