Related:
* TODO:2023-03-04-06-34-28 - Library Native Cleanup
* TODO:2023-03-22-13-18-14 - Refactor: Move `fromString` to enum init

Summary:
* Impl. `UIBlurEffect+Init`.
* Remove `/UIBlurEffect+Helpers`.
* Replace `UIBlurEffect+Helpers` + `UIBlurEffect.Style.fromString` usage w/  `UIBlurEffect+Init` `UIBlurEffect.Style` + `UIBlurEffect.Style.init`.
