13525e0c248eab9b199583cde76430c6da2426e2 rpc: add arg helper unit test (stickies-v)
Pull request description:
Adds string overloads for the `RPCHelpMan::Arg` and `RPCHelpMan::MaybeArg` helpers to be able to access RPC arguments by name instead of index number. Especially in RPCs with a large number of parameters, this can be quite helpful.
Example usage:
```cpp
const auto action{self.Arg<std::string>("action")};
```
Most of the LoC is adding test coverage and documentation updates. No behaviour change.
An alternative approach to #27788 with significantly less overhaul.

Code review ACK 30a6c999351041d6a1e8712a9659be1296a1b46a. Nice change! Implementation is surprisingly simple and additional unit test coverage is welcome, too.
