GIT_SILENT

It's used unconditionally later on

Make sure it fails at the appropriate time when not found

The pipeline stages are also now properly managed, which should prevent
use-after-free errors.

BUG: 453026

Task: https://phabricator.kde.org/T7289

This makes KWin switch to in-tree copy of KWaylandServer codebase.

KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.

When we do more color management stuff we'll need it in more places,
making it a hard requirement reduces the amount of needed ifdefs and
should make adding color management features a little simpler.

Allows removing some CMake checks config-kwin.h contents. This is
supported by all compilers and required for C++17. While touching those
lines I also cleaned up an unnecessary HAVE_UNISTD_H check (glibc always
has it and and incorrect use of HAVE_SYS_PROCCTL_H.

fbdev has been deprecated and unmaintained for a while. With Linux 5.14
including SimpleDRM driver, we can drop it. (at the time of writing this
commit message, the latest Linux version is 5.16).

kwin disables ptrace for a good reason - to prevent other processes from
attaching to kwin and snooping sensitive data or taking control of kwin.
But, that will also make things such as memory statistics unavailable to
read, etc.

On the other hand, the supported platforms where kwin runs all have
security measures in places to forbid shady processes ptrace'ing kwin.
For example, on Linux it's YAMA.

On Linux, by default, a process can ptrace only its descendants. For
example, this can be used by debuggers; otherwise you would need to be
the superuser to attach to any process.

This change drops our ptrace logic in favor of system provided security
measures. It allows the System Monitor to gather kwin's memory usage
statistics and also simplifies code, the current debugger detection
logic is not really robust.

If the system provided security measures are proven to be insufficient,
we can add the ptrace disabling logic back, but it would be great to
avoid that because system monitor won't be able to gather resource usage
statistics, which can be useful for detecting memory leaks in plasma
wayland session, etc.

Notifications are really only useful in a setting with a full

Allows to build KWin without lockscreen support and thus drops the

Otherwise we get lots of moc warnings about there not being any relevant macro used

The ifdefs for have_gbm obfuscate the code unnecessarily - the drm backend
is not a great experience with qpainter, so in practice noone should ship
it without gbm anyways.

The proprietary NVidia driver now supports gbm, which vastly improves the
user experience. For older devices that will not get gbm support dropping
EglStreams will likely not have a big impact as it has several session breaking
issues anyways.

By removing the backend a lot of logic can be simplified, most notably multi-gpu.

wayland platform plugin uses KF::Wayland.

It doesn't build against the stricter 5.85 level
