[GTK][AC] Implement opacity animation with clutter ac backend

Source/WebCore:

Implement opacity animation with clutter ac backend.
Almost all implementations of GraphicsLayerClutter are based on mac port's one.
PlatformClutterAnimation interfaces are also similar with mac port, but they are implemented
with native clutter APIs.
This patch includes only opacity animation related changes, so many APIs might be empty.
Remained animations like rotation and translate will be dealt in another patches.

Covered by existing animation tests.
