  [GTK] Remove the fallback code when GTK fails to create the GL context under wayland
https://bugs.webkit.org/show_bug.cgi?id=253233

Reviewed by Adrian Perez de Castro.

If GTK can't do hardware acceleration (which is quite unlikely) it's
better to to just disable acceleration in Webkit too, instead of using
the glReadPixels fallback solution that is slow and mostly untested.
