Please prepare for ANGLE support of Microsoft Edge

[cx20]

The following is the display result of WebGL Report on Microsoft Edge of Windows 10 Insider Preview 17093.

I noticed that ANGLE is supported in the item of Unmasked Renderer. However, the judgment of ANGLE is No. I think that it is good to do ANGLE detection with the Unmasked Renderer.

We have some vague heuristics that try to guess the presence of ANGLE without an unmasked renderer, that I guess will need to be updated.

@pjcozzi Any insights into what the new rules should be?

No, but all I did last time was just run WebGL Report in different scenarios and see what the most unique difference was - could work again here.

I found a sample of WEBGL_debug_renderer_info(Unmasked Renderer) on the following blog. I think that this information can be used to judge ANGLE and DirectX.

ANGLE is used almost everywhere now. For example ANGLE is used on Safari on MacOS

Also, the current check under the WebGL2 tab it will say "ANGLE: Yes, D3D9" but WebGL2 support requires D3D11

Given that ANGLE is used almost everywhere I'd suggest you just get rid of parts about ANGLE.
