ClipToBounds on parent control is not clipping childrens visual while enabled Compositor

Describe the bug In avaloniaUI you can clip childrens by enabling ClipToBounds property on parent control, additional supports clipping rounded corner. But there was a problem while I want clip corner in AvaloniaUI 11.0, it completely broken and you could see some unclipped corner on parent visual.

To Reproduce Steps to reproduce the behavior:

1. Create a new project with Avalonia package, version 11.0-preview1
2. Add a control, might be border, or any control supports CornerRadius property and clipping
3. Add some childrens in parent control (with Panel wrapping), and fill them with colors
4. Enable ClipToBounds in parent control, set CornerRadius 16 (or whatever numbers you want, but minimum 4)
5. Run program, you will see such glitch I described in this issue.

or you can use project from my glitch reproduce repository

Expected behavior Parent control or visual should clip childrens and applying rounded corners clipping with compositor enabled. something like this:

In reproduce project:

Desktop (please complete the following information):

• OS: Windows 10 Professional 21H2
• Version: Avalonia 11.0.0-preview-1

Additional context Actually it can be fixed by disable compositor, but it supposed to work as well while compositor is enabled. Add above code to AppBuilder chain and you will disable compositor.

...
.With(new Win32PlatformOptions
{
    UseCompositor = false
})
...

Also, how to disable compositor in a mobile Android project?

Hi! Use AndroidPlatformOptions instead of Win32PlatformOptions:

.With(new AndroidPlatformOptions
{
    UseCompositor = false
})

Please refer AndroidPlatform.cs#L76 to know which avaloniaUI options have for Android platform
