Render Avalonia into 3d textures using Skia with ANGLE backend

[tebjan]

existing implementation to check: https://github.com/TheKeyblader/Stridelonia

Avalonia Skia gpu setup:
https://github.com/AvaloniaUI/Avalonia/tree/master/src/Skia/Avalonia.Skia/Gpu

GPU implementation for WebGL as an example:
https://github.com/AvaloniaUI/Avalonia/blob/master/src/Web/Avalonia.Web.Blazor/BlazorSingleViewLifetime.cs
https://github.com/AvaloniaUI/Avalonia/blob/master/src/Web/Avalonia.Web.Blazor/BlazorSkiaGpu.cs

Also interesting for running skia with ANGLE:
mono/SkiaSharp#745
https://github.com/mono/SkiaSharp/tree/main/source/SkiaSharp.Views/SkiaSharp.Views.UWP/GlesInterop
https://hg.mozilla.org/mozilla-central/file/tip/gfx/gl/SharedSurfaceD3D11Interop.cpp

Step 2:
if we got Skia GPU images from a shared texture handle, we can also render 3d content into an Avalonia app.

Avalonia already have code about angle

Avalonia also supports rendering with Direct2D. Wouldn't it make more sense to go that route? At least in my experience Skia tends to cause performance problems.
Found this video. It's pretty old so don't know if things are still the same / comparable, but judging from it Avalonia + Direct2d looks like a clear winner.
