Use the browser compositor for drawing windows on WASM

Make the browser compositor draw the window non-client area (using css
+ html). Get rid of OpenGL usage in non-OpenGL windows and use canvas
2d context instead to blit the texture (QImage).

Also, as part of the change, remove the deprecated canvas element support
in QScreen.
