Notify layers that their animations have started when we flush the context, not when we render

r76372 separated context flushing from rendering, but this bit of code got left behind.

Reviewed by Sam Weinig.

* platform/graphics/ca/win/CACFLayerTreeHost.cpp:
(WebCore::CACFLayerTreeHost::render): Moved code to notify the layers from here to
notifyAnimationsStarted.
(WebCore::CACFLayerTreeHost::flushPendingLayerChangesNow): Added a call to
notifyAnimationsStarted after we flush the context.
(WebCore::CACFLayerTreeHost::notifyAnimationsStarted): Added. Code came from render. Changed
to call PlatformCALayer::animationStarted rather than calling through to the client
directly.

* platform/graphics/ca/win/CACFLayerTreeHost.h: Added notifyAniamtionsStarted.
