We would get the MetaDisplay from the backend singleton before creating
the MetaCompositor, then in MetaCompositor, get the backend singleton
again to get the stage. To get rid of the extra singleton fetching, just
pass the backend the MetaCompositor constructors, and fetch the stage
directly from the backend everytime it's needed.
This also makes it available earlier than before, as we didn't set our
instance private stage pointer until the manage() call.

MetaCompositor is the place in mutter that manages the higher level
state of compositing, such as handling what happens before and after
paint. In order for other units that depend on having a compositor
instance active, but should be initialized before the X11 implementation
of MetaCompositor registers as a X11 compositing manager, split the
initialization of compositing into two steps:
1) Instantiate the object - only construct the instance, making it
possible for users to start listening to signals etc
2) Manage - this e.g. establishes the compositor as the X11 compositing
manager and similar things.
This will enable us to put compositing dependent scattered global
variables into a MetaCompositor owned object.
For now, compositor management is internally done by calling a new
`meta_compositor_do_manage()`, as right now we can't change the API of
`meta_compositor_manage()` as it is public. For the next version, manual
management of compositing will removed from the public API, and only
managed internally.

Given that on Wayland we are pretty much guaranteed to finish MetaX11Display
setup after the MetaCompositor is enabled, we may drop the
meta_compositor_manage() x11 initialization bits, and move them into the
MetaX11Compositor subclass where it's actually needed.

Move out updating of various shapes (input, opaque, shape) indirectly
from X11 to the corresponding X11 sub types of MetaWindowActor and
MetaSurfaceActor.
Also move fullscreen window unredirection code with it. We want to
effectively do something similar for MetaCompositorServer, but it will
work differently enough not to share too much logic.
While it would have been nice to move things piece by piece, things were
too intertwined to make it feasible.
This has the side effect fixing accidentally and arbitrarily adding
server side shadow to Wayland surfaces.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendX11, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

A base type shouldn't know about sub types, so let MetaDisplay make
the correct choice of what type of MetaCompositor it should create. No
other semantical changes introduced.

Introduce MetaCompositorX11, dealing with being a X11 compositor, and
MetaCompositorServer, being a compositor while also being the display
server itself, e.g. a Wayland display server.
