These might (?) have been necessary for VS builds, but we don't need
them any longer.

This test is timing out on all platforms and there's no obvious cause.

The new animations engine doesn't need to use StyleChangeFromRenderer

The old animation engine needed to use this because the animation was
updated inside RenderObject::setAnimatableStyle, but the new engine
handles animation updates inside Element::styleForRenderer() and the
StyleResolver so we don't need to force a style change if there's
nothing that actually changed.

This patch removes usage of this flag as the first step of getting rid
of this flag entirely. Forcing a new RenderStyle through the styleWillChange
and styleDidChange machinery when nothing actually changed is not something
we should support.
