Summary:
Most platforms like the nested and virtual do not handle the outputs
themselves and WaylandServer announces the Outputs to Wayland.
So far this was static: at startup it got announced once to Wayland
and any changes were not catched.
This change makes WaylandServer listen to changes to the Screens and
sync them to Wayland.
Unfortunately KWin's internal Screen information is not sufficient to
properly synchronize this to Wayland and also Wayland by not supporting
adding/removing modes does not help.
Thus the solution implemented here is to add new outputs reflecting the
changes and then removing the old ones. This creates situations with more
outputs being present than actually there, but prevents that there are
no outputs at all.
Test Plan: Auto test added which verifies this for the virtual platform

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.

A signal is added to the VirtualBackend to change all screen geometries.
This can be used from auto tests to change the screens. But it's not yet
correctly reflected in other areas. E.g. not forwarded to Wayland Output,
etc.
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/
