Martin Gräßlin c3cf4482a3 Move GLX detection from kwinglobals to CompositingPrefs
Removes the Extension::glxAvailable() from kwinglobals and
implements the functionality in CompositingPrefs, where it
is only needed. There used to be one additional check in
scene_opengl_glx.cpp which is moved into composite.cpp
before the OpenGL Scene is created.
