On wayland, we know we're always going to load our internal QPA. Instead
of shipping a plugin and loading it dynamically we can use Qt static
plugins.
This should result in slightly faster load times, but also reduce the
number of moving pieces for kwin.
This also prevents anyone outside kwin loading our QPA which wouldn't
have made any sense and just crashed.
This makes our QPlatformOpenGLContext private subclass simpler.
As a slightly unrelated change, this patch also fixes a bug where our
platform opengl context may return a wrong surface format if surfaceless
contexts are unsupported.
Summary: Qt is already providing the cmake files to load them, we just need to load them properly.

Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.
A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.
The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes
all of it.
Summary:
Depending on whether the underlying platform supports offscreen surfaces,
QOffscreenSurface may create an invisible QWindow. In our case that's the
case, for each offscreen surface a native window is created. This may
lead to some funky results related to window decorations, see bug 407612.
There are several ways to implement offscreen surfaces - either use pbuffers
or utilize a surfaceless context extension. For the sake of simplicity
this change sticks with pbuffers, but it's a good idea to support both
methods.

Summary:
Using the Wayland protocol for OpenGL is no longer used or useful. KWin
internal windows only use OpenGL through QtQuick. We either have the
sharing context (KWin uses OpenGL for compositing) or we have the
QPainter compositor which also turns QtQuick to use software renderer.
Thus a situation where the Wayland platform context is useful doesn't
exist any more. Removing it helps getting the QPA plugin Wayland free.
Test Plan:
Run nested KWin triggering Outline once with OpenGL and once
with QPainter compositor.

Summary:
This is a preparation step to move this to ECM (or possibly CMake),
which makes sense now that qtbase is using this too (for Qt6).

This makes QCursor::pos and QCursor::setPos function correctly. KWin
actually wouldn't need it as KWin has the KWin::Cursor replacement, but
it allows Qt internal API to have it function correctly and also the
zoom effect does use QCursor::setPos.
This is needed to make KWin build-able on non-Linux, but is actually
only a workaround. The dependency should also be available on non-Linux.
This disables the EGL integration in the Wayland backend (QPainter still
available) and the EGL fallback in the qpa plugin (preferred context
sharing still available, but requires a working OpenGL Scene).

This introduces an own QPA plugin for KWin. QtWayland's plugin is not
a good solution for KWin as QtWayland is meant for Wayland clients and
not for a Wayland server. Given that it makes more sense to have a very
minimal QPA plugin which supports the use cases we actually have.
With our own QPA plugin we should be able to improve the following
areas:
* no need to create Wayland server before QApplication
* Qt::BypassWindowManagerHint can be supported
* no workaround for creating OpenGL context in main thread
* sharing OpenGL context with Qt
* OpenGL context for Qt on libhybris backend
The plugin supports so far the following features:
* creating a QPlatformWindow using KWayland::Client (ShellSurface)
* creating a QPlatformBackingStore using a ShmPool
* creating a QPlatformOpenGLContext with Wayland::EGL
* or creating a QPlatformOpenGLContext which shares with KWin's scene
* creating a QPlatformScreen for each KWayland::Client::Output
* QPlatformNativeInterface compatible to QtWayland
