I started fixing #1559 and decided to rework our `TypeConverter` infrastructure a bit.
This PR renames `AvaloniaDefaultTypeConverters` to `AvaloniaTypeConverters` and allow registration of 3rd party converters here.
`AvaloniaTypeConverters` improves upon the type converter functionality in the BCL by providing the followinng extra functionality:
- Allow registering non-constructed generic types (such as `AvaloniaList<>`) - `AvaloniaTypeConverters` will do the sensible thing and create an `AvaloniaListConverter<T>` with the correct type
- If no type converter is provided, look for a a static `Parse(string)` method which can be used to create an implicit type converter
This allows us to remove a bunch of `TypeConverter`s which just called the relevant `Parse` method.
Fixes#1559
Makes Avalonia more like other XAML frameworks, in that any avalonia property can now be set anywhere. The XAML parser however will only allow you to set registered properties.
Moved Validation Error tracking to attached an attached property
Created an shared error indicator that can be simply added to control
templates and re-styled across all controls
This should reduce the need for code and markup duplication while
allowing for a consistent visual interface
The test .cs files stay in the `Avalonia.RenderTests` directory but the D2D and Skia render test .csprojs are moved to their own directory: include the test files by using a glob in the .csproj.
This avoids the hack we were having to do to get `BaseIntermediateOutputPath` to work - we no longer have this problem as now each .csproj has its own directory, it can use the default directory for intermediate files.
