8d0554e45a [scripting] Allow effects to grab windows
Summary:
Some JavaScript based effects need to grab particular windows in order
to avoid conflicts with other effects.

Example usage:

```lang=js
effects.windowAdded.connect(function (window) {
    if (effect.grab(window, Effect.WindowAddedGrabRole)) {
        window.coolWindowTypeAnimation = animate({
            ...
        });
    }
});
```

a281f2bce1 [effects/dialogparent] Fix flickering of parent windows
Summary:
If a modal window is closed and some alternative effect that animates
the disappearing of windows is enabled(e.g. the Glide effect, or the
Scale effect), the Dialog Parent effect can cause flickering of the
parent window because its animation duration doesn't match duration of
those alternative effects.

Also, if the Fade effect, the Glide effect, and the Scale effect are
disabled, the Dialog Parent will keep the parent window alive for no
good reason.

This change addresses that problem by adding keepAlive property to
`animate` function so scripted effects have more control over lifetime
of animated windows.

If both a modal window and its parent window are closed at the same time
(and there is no effect that animates the disappearing of windows), the
Dialog Parent will stop immediately(because windowDeleted will be
emitted right after windowClosed signal).

If both a modal window and its parent window are closed at the same time
(and there is effect that animates the disappearing of windows), the
Dialog Parent won't reference the latter window. Thus, it won't cause
flickering. I.e. it will "passively" animate parent windows.

99b33e7428 [libkwineffects] Expose getting/setting activeFullScript to scripted effects
Summary:
Getter is exposed as a property on scripted effect in a way that hides
pointers from the scripting side.

Setter is implicitly handled as a property of newly created animations
and holds the activeFullScreenEffect whilst any of them are active. Like
existing effects it remains up to the effect author to avoid the
problems of multiple full screen effects. The RAII lock pattern is
somewhat overkill currently, but it's the direction I hope we can take
EffectsHandler in next API break.

This patch is against the QJSEngine port, though it's not conceptually a
requirement.

3332b32101 [scripting] Fix effect.animate() curve argument being actually used
Summary:
One cannot use a non metatype frrom an external class inside an
invokable. https://bugreports.qt.io/browse/QTBUG-58454

End result is the script engine arguments wouldn't match up and MOC
would just use the default value.

As far as I can tell this has been broken for 6 years.
The global animate method that unboxes a QJSValue as an object is
unaffected.
No shipped kwin effect actually used it.

To some extent we didn't even actually want to enforce the enum as we
also accept custom value of ScriptedEffect::GuassianCurve, so it has
been switched for an int.

Test Plan: Unit test

Ready for QJSEngine port and upcoming other fixes.
Split as it makes it easier to do any before/after testing.

Test Plan:
All tests pass with the current QScriptEngine
Verified expected API against a wiki page and current code.
