Move iOS and macOS implementations to a shared folder called `apple`, to allow
us to reduce the code-duplication between these platforms in the future.
The folder structure is now:
- `src/platform_impl/apple/`
- `appkit/`
- `uikit/`
- `example_shared_file.rs`
- `mod.rs`
* Add preliminary support for tvOS, watchOS and visionOS
* Reduce duplication in Cargo.toml when specifying dependencies
* Add Redox OS support
* Simplify control flow usage
* Apply more recommendations
* Update naming to indicate that Orbital is a platform
* Adjust import order
* Add CODEOWNERS file
This makes it very clear when you're stepping down from the post as a maintainer, and makes it clear for users who is expected to review their PR
* Fix grammar
* Make @kchibisov receive pings for the X11 platform
* Fix typo
