Bug 1414713 - EditorUtils::IsDescendantOf() should take EditorDOMPoint and EditorRawDOMPoint as out param r=catalinb,m_kato 

EditorUtils::IsDescendantOf() current takes a pointer to offset or a pointer to
child content if the caller needs to know the child of the most ancestor node.

However, some callers should get a child as EditorDOMPoint or EditorRawDOMPoint.
Then, they can be used for some editor methods which need to take child node
for performance optimization.

This patch makes EditorUtils::IsDescendantOf() as only two overloads.  One takes
pointer to EditorRawDOMPoint as optional out argument.  The other takes pointer
to EditorDOMPoint as an out param.

Additionally, this creates new constructor of AutoTrackDOMPoint for making it
can treat EditorDOMPoint directly.
