build: Adds a new opengl-egl-xlib build flavour

With this patch if you ./configure clutter using
--with-flavour=opengl-egl-xlib then it will use EGL + OpenGL instead of
the default GLX and OpenGL.

These days upstream driver work is more focused on improving EGL than it
is GLX so likewise we want to make sure Clutter has good support for
EGL.
