At the moment, if an effect wants to have a configure button in the
desktop effects kcm, it needs to add X-KDE-PluginKeyword field with
its plugin id. This is confusing.
This change ports scripted effects to X-KDE-ConfigModule, which is more
intuitive than X-KDE-PluginKeyword.
kcm_kwin4_genericscriptedconfig is a special config module that loads
config.ui from KPackage. However, an effect can specify a different
config module in the metadata if kcm_kwin4_genericscriptedconfig doesn't
suit their needs.
QuickSceneEffect can also be instantiated by C++, for example that's
the case with the overview effect. In that case, qmlContext() is not
going to return a valid context because the effect has not been created
by a QQmlEngine. In that case, use the root context as the parent
context.

oldPos: On QEvent::HoverEnter events, this position will always be QPoint(-1, -1).
pos: On QEvent::HoverLeave events, this position will always be QPoint(-1, -1).
On the same app, such as Wayland-enabled VS Code, the misgeneration causes the cursor to move to the origin when moving the cursor away from the server side decoration.
There are four usages of this overload, two of them are for the
intentionally disabled "Switch to Next/Previous Desktop" actions and the
rest are for "Switch One Desktop to X" actions. Due to the order they
were added, an empty keybind was set as the default and the actual
keybind is never enabled.
Now there's a QKeySequence argument to this overload, so an unexpected
empty keybind is never added. The two usages of addAction that depend on
this empty keybind behavior now pass in an empty QKeySequence.

This commit makes window filtering optional by providing a checkbox
in Desktop Effects > Overview > Overview Configuration KCM. The
referenced bug report describes a bunch of the reasons why people
wanted this option.

with itemChange watching SceneChange is more efficient than connecting
to the windowChanged signal, also this won't arrive during teardown,
aoiding the "destructor already ran" assert.
It would be the case upon lid close which would make KWin crash. Also
adds an assert so in case it happened again we would be able to catch it
easily. It gets applied asynchronously so it needs to be chased down.
In springmotion.cpp for the slide plugin, there are issues when
animations are disabled, namely a black screen flicker.
The flicker is caused by float under/overflow (div-by-0 -> infinity).
This commit fixes that by special-casing an infinite spring constant,
so that the animation immediately jumps to the anchor.
