egui_web: always use the glow painter, and remove the old WebGL code. (#1356)

Browse Source 
* egui_web: always use the glow painter, and remove the old WebGL code.
* Clean up the WebPainter trait
* Clarify WebGL1 warning text in color test

The glow painter became standard in egui 0.17, and I've heard no complaints! So let's simplify and go all in on glow.
