accounts/abi: allow overloaded argument names (#21060)

Browse Source 
* accounts/abi: allow overloaded argument names

In solidity it is possible to create the following contract:
```
contract Overloader {
    struct F { uint _f; uint __f; uint f; }
    function f(F memory f) public {}
}
```
This however resulted in a panic in the abi package.

* accounts/abi fixed error handling
