785e1407b0 wallet: Use util::Error throughout AddWalletDescriptor (Ava Chow)

Pull request description:

  #32023 changed `AddWalletDescriptor` to return `util::Error`, but did not change all of the failure cases to do so. This may result in some callers continuing when there was actually an error. Unify all of the failure cases to use `util::Error` so that all callers handle `AddWalletDescriptor` errors in the same way.

  The encapsulated return type is changed from `ScriptPubKeyMan*` to `std::reference_wrapper<DescriptorScriptPubKeyMan>`. This avoids having a value that can be interpreted as a bool, and also removes the need to constantly dynamic_cast the returned value. The only kind of `ScriptPubKeyMan` that can come out of `AddWalletDescriptor` is a `DescriptorScriptPubKeyMan` anyways.
