Summary:
Recently we noticed that there are multiple areas where KWin needs to
inform the user about how to operate. Examples are:
* Screenshot
* ColorPicker
* Pointer constraint enabled
* Pointer constraint about to be removed
* Kill Window
For Screenshot and ColorPicker we used an EffectFrame to render it. But
this is not an optimal solution as it's lacking many features we would
need. We cannot properly use it from within KWin core, we cannot
implement features like hide on mouse over, etc. etc.
This change introduces an OnScreenNotification which supports:
* showing an icon
* showing a message
* timeout
It is Qml styled, so that it can be easily adjusted. This is a big
improvement over the EffectFrame solution. The Qml file creates a Plasma
Dialog of type OSD. Thus KWin places it like the normal OSD windows and
also looks kind of similar. In the case of KWin the focus is more on the
message, than an icon, so the icon is placed left of the text.
While the OnScreenNotification is supposed to be used like a singleton,
it doesn't use the KWin singleton pattern. Instead a small wrapper
namespace OSD is introduced which provides a convenient API for KWin
internal areas to show/hide the notification. By not using the KWin
singleton pattern, the OnScreenNotification does not depend on any other
parts of KWin and can be easily unit-tested.
A few features are still missing and will be added in further commits:
* hide-out on mouse over
* optional skip close animation (needed for screenshot)
* X11 support (not that important as it's mostly for Wayland features)

Summary:
The idea is to have KWin provide a virtual keyboard. To support this
KWin uses the QT_IM_MODULE qtvirtualkeyboard and makes sure that the
QPA plugin loads it.
KWin has a new class VirtualKeyboard which acts as the focus object and
the "proxy" for input methods. The QPA plugin ensures that this is the
focusObject, so that all input method related events are sent to this
class. From there it will be possible to delegate to other applications
through the Wayland interfaces.

In order to get all our UI being written in QML, the Outline for
compositing is ported to QtQuick. It creates a QQmlContext and
QQmlComponent and loads the (currently hardcoded) qml file. The context
gets to properties exported: outline. The outline property allows the qml
to get the geometry it should use. The QQmlEngine is used from Scripting
thus all general scripting properties are exported (e.g. workspace).
The qml script is expected to create a QQuickWindow as it's root item
and style it.
The qml file is stored in a new qml subdirectory. The idea is that each
of the qml types we have gets an own directory there and for each
implementation there should be a further subdirectory.
Thus we have outline/plasma/ with outline being the type and plasma
being the implementation. But at the moment the script location is still
hardcoded.
