So far the DrmOutput connected to all input events when going into
power saving. As we now have the input filters it's better to just
install a filter when an output goes into powersave and remove the
input filter again when all outputs are enabled again.
To make this work InputRedirection gains a new method to add a new
filter as the first filter. This is a potentially dangerous method
as it allows to have a filter before LockScreenFilter gets the
events. But in case of DPMS it's something we actually want.
A nice new feature possible with the input filter is that we can
filter out the event which re-enables the outputs. Thus when getting
on a system with output off and screen locked, the first key hit
doesn't go to the lock screen.

BUG: 341201
Fixed-in: 5.6.0 (Wayland-only)
Begin of proper multiscreen support!
We load configuration sets for the connected outputs. Each set of
screens represents a unique configuration. For that we use the md5
sum of the edid+connector as uuid of an output. Each of the md5 sums
is then used to create a uuid of the output set. We can be quite certain
that this will generate unique ids for the use cases we will face.
The uuids are used as group names. And from there we read the global
position.
The uuids are considered internal information. It is not intended for
users to configure manually in the config file. The intended way to
configure will be the OutputManagementInterface which recently got added
to KWayland. Once KWin applies a configuration it will store it to config
so that it can be loaded on next startup.
The configuration looks like:
[DrmOutputs][abcdef0123][0123abcdef]
Position=0,0
[DrmOutputs][abcdef0123][fbca3bcdef]
Position=1280,0
This is an example for two outputs set next to each other.

Our server announces the DpmsManagerInterface and in the DRM backend
we announce support for Dpms on the OutputInterface (if the Output
supports it) and we connect to changing Dpms requests.
If an Output went into DPMS standby we need to re-enable the Output
once we get any input event.
For this we connect to the signals of InputRedirection once we go
to standby. Once we enable again, we disconnect (to not handle the
events all the time), blank the screen (initial modesetting) and
trigger a complete repaint.
During cleanup the KWayland::OutputInterface is already destroyed before
we hit the cleanup code of DrmOutput. Thus guard with a QPointer to not
delete twice.
Replaces the functionality of the WaylandBackend and makes it available
to all backends by providing the functionality directly in
AbstractBackend. By default a backend is not ready and the implementation
must call setReady(true) to indicate that setup has finished
successfully. The compositor won't start till the backend indicates that
it is ready.
The aim is to be able to create a plugin for each of the backends.
The following directories are created:
* backends/drm
* backends/fbdev
* backends/wayland
* backends/x11
