Describe the bug

When defining styles, if the user wants to reference the Styles owner in a setter, not providing a selector will reference the owner, in other words, it's implicit "self". Currently this doesn't work and crashes when set in xaml with the error
Could not determine target type of Setter Line Y, position X

To Reproduce

Add a style with no selector to a control.

  <UserControl.Styles>
    <Styles>
      <Style>
        <Setter Property="IsVisible" Value="False"/>
      </Style>
    </Styles>
  </UserControl.Styles>

Expected behavior

The setter finds the target type, which is the Styles owner, and sets IsVisible property on the control.
This issue can be worked around by setting x:SetterTargetType on the setter, but as there's an explicit test available for this in code form, xaml should also behave the same: https://github.com/AvaloniaUI/Avalonia/blob/master/tests/Avalonia.Base.UnitTests/Styling/StyleTests.cs#L81 .
