[cogl] Move the EGL GDL winsys out of cogl-winsys-egl

[Neil Roberts <nroberts src gnome org>]

commit d70c764da6c4bd562e76cc68a4c977b671393de1

    Move the EGL GDL winsys out of cogl-winsys-egl
    
    This moves all of the code specific to the gdl winsys out of
    cogl-winsys-egl. It is completely untested apart from that it
    compiles.
