Make all CoglOnscreen sub types inherit CoglOnscreen

Browse Source 
Thins means that e.g. MetaOnscreenNative now inherits CoglOnscreenEgl,
which inherits CoglOnscreen which inherits CoglFramebuffer, all being
the same GObject instance.

This makes it necessary to the one creating the onscreen to know what it
wants to create. For the X11 backend, the type of renderer (Xlib EGL or
GLX) determines the type, and for the native backend, it's currently
always MetaOnscreenNative.

The "winsys" vfunc entries related to onscreens hasn't been moved yet,
that will come later.

CoglPipeline is used to render to it. Eventually we may want to
