feat: add FromStr to ZkSolcWarnings and ZkSolcErrors

[elfedy]

This is required to parse suppressed error/warnings from cli arguments, so users can pass for example --zk-suppressed-warnings txorigin while also failing when passing an invalid value (Else we need to either silently pass nothing or panic)

Hmm I'd opt to store this as strings actually, and pass them untypedly to the compiler.
For now we have only these 2 but perhaps in the future more will be added (or removed), so I'd prefer to keep this decoupled

@Karrq I guess the place to discuss this was this previous PR and not here? @hedgar2017 your call probably on this though since we will probably end up using that common crate for zksolc settings. I don't have strong feelings either way.

As a user if I run --help I expect to see the options I can use, and for that it always makes sense that libraries provide the concrete types which are string serializable, and not just free form text.

However, if we expect this field to change quite a bit we can implement it as a pass-through, but that would be the anti-pattern.

Hey @elfedy - I've moved everything including these structs to this crate.
Please let me know if you need anything to start using it!
There can be some derives missing, so feel free to drop them there with a quick PR.

[hedgar2017]

Approving for now for the sake of unblocking, but please start migrating to our common definitions!
