Adds two attributes which describe the stability of an API:
- `UnstableAttribute` indicates that we provide no API stability guarantees for the class between minor/patch versions. This is mostly applied to `*Impl` interfaces which describe the interface between core Avalonia and platform implementations
- `NotClientImplementableAttribute` indicates that an interface is stable for consumption by a client, but should not be implemented outside of Avalonia itself (either because custom implementations are not supported, or because as members may be added to its API)
* Merge core libraries.
Everything below `Avalonia.Controls` into `Avalonia.Base`.
* Move new files to correct place.
* Removed unused dirs/projects,

Now that more unit tests are present in Avalonia.Base.UnitTests, general `AvaloniaObject` properties are getting registered. Ignore those.
