Enable GL on Windows ARM

[mattleibow]

Description of Change

This PR just removes the code that prevents OpenGL from working on Windows ARM.

This was initially done in mono/skia@0c75727. The reason for this was there was no OpenGL on ARM. However, recently, there is a way: https://apps.microsoft.com/detail/9nqpsl29bfff

The reason we can just remove this code is because we don't actually link with opengl32 directly and instead load it at runtime.

The good new s is that this now works! But, the views do not as the yare using OpenTK which uses glfw, and that is not yet built for ARM. I will play with that, but chances are for now we will wait for glfw/glfw#2163

Hi folks,

The builds are now available on the preview feed: https://aka.ms/skiasharp-eap/index.json
Let me know if version 3.119.0-preview.0.38 is now working again for you.

As soon as you let me know, I can release this to NuGet and then hopefully a stable version shortly afterwards.

Hi @mattleibow . I think I posted our update elsewhere but just saw this. We have tested the preview build and it works as expected. A stable build with this fix would be much appreciated! Thanks!
