feat: [mason_logger] support validation for `prompt`, `promptAny`, and `chooseAny`

**Description** `Logger` has some user inputs that accept arbitrary data. It can be useful to validate that user input "inline" with a given user input without having to re-prompt the user for an input. **Requirements** - [ ] define `Validator<T>` typedef like [Flutter's `FormFieldValidator`](https://api.flutter.dev/flutter/widgets/FormFieldValidator.html)<T>. - [ ] add optional `Validator<String>? validator` parameter to `Logger.prompt` - [ ] add optional `Validator<List<String>>? validator` parameter to `Logger.promptAny` - [ ] add optional `Validator<List<T>>? validator` parameter to `Logger.chooseAny` **Additional Context** > Why these methods? I think these are the only places a validation makes sense since data types are not very constrained compored to the other inputs. - `chooseOne` is already very limiting with select one (how would you validate "one" item?). - `confirm`'s return value is it's "validation" by nature of booleans. "Inline" validation does seem to provide any additional information to the user. > How would this work? ```dart void collectInput() { String value = }
