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,
* Removed outdated references from theme assemblies.
* Merge unit tests to match new assembly layout.
* Fixup test namespaces.
* Make directory match namespace.
* Move files to match namespace.
* Move files to match namespace.
* Fix up incorrect namespace.
`Avalonia.Visuals.Media.Imaging` -> `Avalonia.Media.Imaging`.
* Fix resource URL.
* Removed outdated dependencies.
* Added missing project reference.
* Update test namespaces.
* Fix merge error.
* Fix merge errors.
* Fix bad merge in WindowsInteropTest.csproj.
* Fix up merge errors in csprojs.
* Remove merged tests from nuke.
* Fix up namespace.
* Fix compile error.
* Fix failing tests.
Now that more unit tests are present in Avalonia.Base.UnitTests, general `AvaloniaObject` properties are getting registered. Ignore those.

The Nullable annotations on netstandard2.0 are incomplete and incorrect in places. Ignore nullable warnings on netstandard2.0 and make them errors on later target frameworks.
Now we're multitargeting `netstandard2.0;net6.0` hardcoding this to `netstandard2.0` doesn't work, as the version that gets built will depend on the target framework being compiled.
