Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking
In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.
In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.
The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.
Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.
To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.
The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.
This basic interaction is also ensured through an added auto test.
This change implements T4605.
Test Plan: Added auto test and nested KWin Wayland with D3488

Summary:
So far when KWin intercepted a key event a leave was not sent to the
Wayland surface currently having keyboard focus. This could result in
the Wayland application to start repeating keys. E.g.
1. application gets key press event
2. This triggers an internal window to show
3. key release goes to KWin internal window
4. application starts to repeat key as there is no release
With this change whenever KWin intercepts the key event e.g. due to
* internal window
* Effects grabbing key event
* Tabbox
the focused keyboard surface is set to null, thus triggering a leave
event and the client not starting to repeat the event.

Summary:
The WaylandServer creates the XdgShellV5 interface and hooks it up
to create a ShellSurface whenever an xdg surface or xdg popup is created.
ShellClient gains some new ctors for the different variants and is
adjusted to delegate to xdg surface respectively.
With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

Summary:
Many tests create a Wayland window, render it and then wait till it's
created in KWin as a ShellClient. To reduce code duplication the test
helper provides helper methods to wait for the next ShellClient to be
shown and to directly render and wait for the window for that to be
shown.

Summary:
A new namespace KWin::Test is added which provides a few helper
functions. It makes it easy to setup a KWayland client connection with
the base set to be able to create a Surface and flags to create
additional interfaces. This replaces the KWayland connection dance in
init() methods. For cleanup() there is also a dedicated helper function.
In addition there are helper functions to:
* render a surface
* create a surface
* create a shell surface
* flush the wayland client connection
* access to the created interfaces - for compatibility with existing code
The idea is to extend this Test library also for other common use cases
like creating an X11 connection and X11 windows, etc.
