Martin Gräßlin a1642a85d3 Allow using EGLOnXBackend with X11WindowedBackend
Mostly refactoring to not take the global X11 information (connection,
display, etc.). Adds a dedicated ctor overload which takes the
X11WindowedBackend.

SceneOpenGL is adjusted to create an EGLOnXBackend instead of Wayland one
if the X11WindowedBackend is used.
