Resolution of abi-coder tests

[petertonysmith94]

Summary

With #3349, we introduced several tests which we skipped at the time for a variety of reasons. It'd be good to resolve all of these to ensure our abi-coder has a full coverage of encoding/decoding.

For types_struct_with_array_of_enums we have an issue with result causing some unexpected behaviour.

For types_struct_with_multiple_struct_params and types_struct_with_complex_nested_struct we encounter issues with the deeply nested types and go unexpected results when returning these for functions:

error: Type "StructD<u32, u32, StructF<Vec<StructG>>>" does not implement AbiEncode or AbiDecode.

types_struct_with_array_of_enums

• We encountered an issue with the results of this function, and all the details can be found in the following issue.
