Benjamin Otte 813e9c95fb gdk: Add Cairo context implementations for all backends 
And make the GdkCairoContext as abstract.

The idea of this and thje following commits is to get rid of all
Cairo code in gdksurface.c (and $backend/gdksurface-$backend.c)
by moving that code into the Cairo context files.
In particular, the GdkSurfaceClass.begin_frame/end_frame()
functions (which are currently exclusively used by the Cairo code
should end up being moved to GdkDrawContextClass.begin/end_frame().

This has multiple benefits:

1. It unifies code between the different drawing contexts.
   GL lives in GLContext, Vulkan in VulkanContext and Cairo in
   CairoContext. In turn, this makes it way easier to reason about
   what's going on in surface-specific code. Currently pretty much
   all backends do things wrong when they want to sync to drawing
   or to the frame clock.

2. It makes the API of GdkSurface smaller. No drawing code (apart
   from creating the contexts) needs to remain.

3. It confines Cairo to the Drawcontext, thereby making it way
   more obvious when backends are still using it in situations
   where it may now conflict with OpenGL (like when doing the dnd
   failed animation or in the APIs that I'm removing in this
   branch).

4. We have 2 very different types of Cairo contexts: The X/win32
   model, where we have a natively supported Cairo backend but do
   double buffering ourselves and use similar surfaces and the
   Wayland/Broadway model where we use image surfaces without any
   Cairo backend support and have to submit the buffers manually.
   By not sharing code between those 2 versions, we can make the
   actual code way smaller. We also get around the need to create
   1x1 image surfaces in the Wayland backend where we pretend
   there's a native Cairo surface.

/**
* SECTION:wayland_interaction
* @Short_description: Wayland backend-specific functions
* @Title: Wayland Interaction
*
* The functions in this section are specific to the GDK Wayland backend.
* To use them, you need to include the `<gdk/gdkwayland.h>` header and use
* the Wayland-specific pkg-config files to build your application (either
* `gdk-wayland-3.0` or `gtk+-wayland-3.0`).
*
* To make your code compile with other GDK backends, guard backend-specific
* calls by an ifdef as follows. Since GDK may be built with multiple
* backends, you should also check for the backend that is in use (e.g. by
* using the GDK_IS_WAYLAND_DISPLAY() macro).
* |[<!-- language="C" -->
