Compositor Animation Timelines: Fix frame swapping tests in WebFrameTest.cpp

We want to enable compositor animation timelines (external cc::AnimationHost) mode by default here:
https://codereview.chromium.org/1308053006/

So we need to notify Page and ScrollingCoordinator on main frame swapping.

Otherwise, the following webkit_unit_tests fail in new mode:

WebFrameTest.SwapMainFrameWhileLoading
WebFrameSwapTest.FramesOfRemoteParentAreIndexable
WebFrameSwapTest.FrameElementInFramesWithRemoteParent

Note that this code works only in --site-per-process mode.
