  -----------
  Move code for computing Intersection Observations from document to IntersectionObserver

Reviewed by Cameron McCormack.

Move most the Intersetion Observer-related code in Document into IntersectionObserver.cpp
for better encapsulation.

The only behavior change is to keep RefPtr to the IntersectionObserver while running the code.
