Summary:
So far KWin does not know which Compositors the platform actually
supports. This results in KWin happily trying to use the OpenGL
compositor on fbdev or the QPainter compositor on hwcomposer although
that is obviously going to fail as the platform doesn't support this.
By adding a pure virtual method all Platforms can define what they
support. In a later step the Compositor can use this to create an
appropriate scene and also perform proper fallback handling in case the
scene creation fails.
Test Plan: Compiles

This change is similar to D7232 and moves the scene_qpainter into a
dedicated plugin. Compared to the XRender case it's more complicated as
the platform plugins need to implement a platform specific backend.
The base implementation for this part used to be in scene_qpainter. As
the idea is to completly move it away from KWin core it would be point
less to still have the backend definition in KWin core, but it cannot
be in the scene plugin as otherwise all platforms need to link the
plugin.
To solve this a new platformsupport subdirectory is added which contains
the scene platform backend as a static library. For the OpenGL scene such
a static library will also be required.
Test Plan: SceneQPainter test still passes, nested compositor still works

Summary:
So far if the framebuffer platform run into an error on initialization
it did not continue and caused the system to freeze. With this change
it properly emits the initFailed signal in all error conditions which
causes kwin_wayland to terminate. This is a much better situation than
just staying in a running, but frozen state.

Summary:
If the format of the framebuffer is BGR we cannot create an RGB image
format from it - the rendering is incorrect. Unfortunately QImage does
not support a BGR image format.
To solve this problem we still use an RGB image format but on rendering
the front buffer is rgbSwapped to convert the RGB image to a BGR image.

Summary:
No need to delegate the painting of the software cursor into the backend.
The core has enough information to perform the rendering itself.
This change means less code duplication and all platforms which might use
a software cursor in QPainter compositor gain support for it without any
further adjustments.

Summary:
Platform::setSoftWareCursor creates connections to the Cursor in order
to trigger repaints whenever the cursor position changes. The Cursor is
created before Platform::init is called, but after the Platform is
created. Thus the call needs to happen in init, otherwise the cursor
is not rendered correctly.

Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.
So new location is plugins/platforms/
