cbbe94d769 Restrict available supported compositors based on first initialized one
Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.

While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.

This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.

Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

d49642ca15 Add touch support to x11 windowed platform
Summary:
This change inits XInput extension, listens for touch events and
forwards them to our platform API. Thus touch events are forwarded on a
nested wayland session on X11.

Please note that I only tested this change on Xwayland.

Test Plan: Run nested kwin_wayland with two outputs and looked into debug console

09489a4c2b Add a pure virtual method to Platform to describe the supported compositors
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.

dec76a77e2 Scale input on windowed backend so input co-ordinate system matches host
Summary:
In theory we shouldn't need to scale input, however when in windowed
mode
we need to convert the host into output normal.

fd58c68ba5 Set wayland output scale
Summary:
Provides a virtual method in Screens where backends can supply the scale
of each screen, this is then set on each output.

For the X windowed backend this value is taken from a command line
parameter.

Test Plan:
Ran windowed mode with --scale 1 and 2
then kate --platform=wayland from another screen.
On the latter case UI elements were scaled up correctly

33dffc0fd7 Move the x11 plugin sources into a x11/windowed directory
Preparation step for having two x11 backends: the windowed for Wayland
and a standalone for kwin_x11.
