Obsolete OpenGLView

[PureWeen]

Description of Change

The OpenGLViewRenderer's were not ported to .NET MAUI and we currently don't have a plan to. They are still available via build.UseMauiCompatibility but they are currently not tested and are unsupported

[jsuarezruiz]

Require some more changes to pass the Build.

One of the big reasons OpenGLView is not so useful anymore is that really devices are "supporting" OpenGL but moving to new things:

• Android is Vulkan
• iOS/macOS is Metal
• Windows is DirectX

Sure, OpenGL "works" but already you can't create Mac Catalyst apps with OpenGL, and iOS and macOS is deprecating it. Android still works, but they are moving towards Vulkan pretty heavily and Windows... well, OpenGL was always a second class citizen.
