[wayland] Add a virtual framebuffer backend A new backend which doesn't present the rendered output. It uses a QPainter scene, renders to a QImage but doesn't present it anywhere. Thus a real virtual backend. By exporting the environment variable KWIN_WAYLAND_VIRTUAL_SCREENSHOTS the backend creates a temporary dir, prints the path to std-out and saves each rendered frame into that directory. Of course with exit it will be deleted again.

[platforms/virtual] Let VirtualOutput inherit Output Summary: Let VirtualOutput be a child class of the new generic class Output. This allows code sharing and a very similar behavior of the Virtual backend in comparision to the Drm backend. Test Plan: Autotests succesful with two exceptions: The decoration input test fails on testDoubleTap, row topLeft. This is to be expected because now the ScreenEdgeInputFilter captures the event at position (0,0) before the DecorationEventFilter can capture it. The autotest was adapted to take this special case into account. Also the lockscreen test fails, because the virtual output is currently missing the physical size yet.

#include "outputscreens.h"
[backends/virtual] Add possibility to have multiple virtual screens Very basic: all screens have same size and are ordered from left to right. It's mostly meant to allow easy test cases with multi-screen. The quick tiling test demonstrates how it's used.

Convert virtual backend to per screen rendering Summary: Output scaling can't ever work on a single buffer; especially if they're different scales and overlapping. This ports the virtual backend to perScreenRendering so that I can use it for tests. ctest fails here, but it fails on the tests that it failed on before..
