Summary:
There are rules that have to be applied only once, e.g. every Remember
and Apply Initially rule, as well rules that need to configure the client,
e.g. size, etc. In the best scenario the compositor would evaluate such
rules when the client is about to be mapped.
This change limits window rules only to xdg-shell clients because right
now only this protocol lets compositors to intervene in the client
initialization process. Also, it makes things a bit easier for us on the
compositor side.
xdg-shell protocol satisfies most of ours requirements to implement window
rules, but not all of them. If the client is about to be mapped for the
second time and its size is forced by a rule, then compositor may need
to configure it. Currently, xdg-shell protocol doesn't have any mechanism
that a client could use to notify the compositor about its intent to map.

Kwin has the same concept of geometry for both window management, input
and rendering.
In order to approach this in a way that does not risk any regressions
with kwin's current structure AbstractClient::geometry remains the
canonical source and we handle the window within that internally within
ShellClient treating the windowGeometry as a set of margins from this.

Summary:
When resizing a window particularly from the left side, we need to
co-ordinate moving the window with when we get the resized buffer.
The code in AbstractClient::handleMoveResize checks
isWaitingForResizSync to make sure we never send more than one resize
request at a time to keep that in sync.
This makes sense on X and wl_shell_surface, but not on XDGShell where we
can track which resize events have been handled by the client.
ShellClient already keeps a stack of our pending configure requests and
handles everything appropriately, we don't need to block.
This results in a smoother dragging experience and avoids a potential
deadlock currently seen when a client may not reply to a no-op configure
request.

By blocking sending configure events we will have flushed the correct

Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.

Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).

Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.
This is something I find unsuited, for the following reasons:
* any test in KWin for functionality set through the plugin would fail
* it's not clear what's going on where
* in worst case some code could deadlock
* KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used
The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.
But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.
To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.
To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.
This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).
As the change could introduce regressions I'm targetting 5.16.
Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

The former can be used to implement typical windows, the ones that can

Currently we process the new position the next time the buffer updates,
but with no guarantee that it has actually tried to resize/whatever yet.
The client could be providing a new buffer just because the contents
have changed.
XDGShell has an acked serial designed to keep everything precisely in
sync. A surface represents the last configure that was acked.
This patch tracks the pending position for each configure and applies it
accordingly.
WL_shell does not have this mechanism, so behaviour is kept the same as
before.

This is a pre-requisite to syncing maximisedState/isFullScreen with the
