Summary:
When windows get added some effects grab the window and want to be the
only one animating this window. For this the grab roles exists. An
effect being notified later on evaluates the grab state and does not
start the animation.
This process failed due to being dependent on the order the effects are
loaded. Window Added/Closed are signals emitted by EffectsHandler, thus
first come, first serve. The requested effect order does not play into
it.
Due to that it could happen that an Effect which should not animate,
started to animate as the grab was still there.
This change adds the possibility to be notified whenever the window data
changes. A new signal is added to EffectsHandler which is emitted
whenever the windowData changes. The interested effects connect to it
and cancel their (just started) animation for the window.
Adjusted effects are:
* ScaleIn
* Fade
* WobblyWindows
In case of WobblyWindows an additional logical error was fixed that the
animations were only run when an effect grabbed instead of the other way
around.

The first test case was sometimes failing due to the time value in the
first render pass being too high. So that the effect ended directly for
the window.
This change adds a small waiting time for the compositor to render prior
to the creation of the window. Ideally we would connect to frameRendered
signal, but the OpenGL compositor doesn't emit it yet.
Test more combinations of other effects together with sliding popups.
The problem does not only exist for scale in but for pretty much any
effect that the ordering in which the effects get loaded makes the test
pass or fail.
Some effects require OpenGL, as build.kde.org does not support OpenGL
compositing (yet), the tests only do the OpenGL cases if an OpenGL
compositor could be created.

The test case loads the sliding popups effect and the scale in effect
which also operates on added windows. As the test case shows depending
on the sequence how the effects are loaded, the window gets animated by
both effects (wrong) oor only sliding popups.
CCBUG: 336866
Summary:
It can happen that startAnimation is invoked multiple times for a
window. In case it was invoked a second time the previous animation was
not cancelled. This resulted in the set-animation to never end. When
closing a window, it would stay around as a translucent, non-interactive
window zombie.
This change ensures that existing animations get cancelled.

Test Plan: Tested through autotest and manually.

This test case simulates a condition of the translucency effect
modifying windows of certain types (e.g. dialogs).
In case the effect got activated for a window it does not end after the
window gets closed and creates a non-interactive zombie window.

Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.
This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.
As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.
The information whether animations are supported comes from the Scene.
It's implemented in the following way:
* XRender: animations are always supported
* QPainter: animations are never supported
* OpenGL: animations are supported, except for software emulation
In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.

Summary:
This fixes a regression introduced with a1afeded6a.
The connections were setup every the windowShown signal got emitted.
This caused effects to get multiple singals and start multiple animations
which then do not get cancelled correctly.
The incorrect behavior was most visible in the translucency effect which
did not cancel the move animation and the window stayed translucent.
BUG: 366081
Test Plan:
New test case which simulates the behavior of the translucency
effect.
