Replace FTN::IsDescendantOf by RFH::IsDescendantOf
A FrameTreeNode hosts several RenderFrameHost like:
* The current RenderFrameHost.
* The future one that is loading but hasn't committed yet.
* The ones pending deletion.
On its turn a RenderFrameHost contains several children frames, represented
by FrameTreeNode.
This CL replace FTN::IsDescendantOf by RFH::IsDescendantOf.
* The new form of IsDescendantOf is used in follow up CLs.
* In the case of one RenderFrameHost being pending deletion, the meaning is a
bit different. For instance during a navigation from A(B) to C. Both
RenderFrameHost A and C are on the same FrameTreeNode. The
FrameTreeNode of B is a child of the FrameTreeNode of C, but B is
not a child of C, only a child of A.
Add a content/public API so that embedders won't have to manually
iterate on RenderFrameHost::GetParent() themselves to get this
information. This will be used in a follow-up CL.
