Feature to allow decoding of call data for contracts that are proxies/diamonds

[startswithaj]

What is needed?

For Users that use proxy contracts or diamonds ERC-2535 the SAFE UI does not decode the transaction data. This is a known issue. Users are also not able to upload the abi for these contracts in anyway.

Feature:

1. In the address book allow users to configure an ABI for the address.
2. In the transaction panel (pictured below) add a button [Decode Data With Custom ABI].

This has been a problem for years for many users. Currently we must use a tool like https://lab.miguelmota.com/ethereum-input-data-decoder/example/ to verify call data or other custom tooling

Alternative:

Add a button that uses the https://www.4byte.directory/ or https://openchain.xyz/signatures api to check if there is a result for the function signature and if found use it to decode the call data.
