Split S2Edge and UndirectedEdge up to make equals() method correct.
Before this CL it was possible to have instances of S2Edge such that:
a.equals(b) ==/==> b.equals(a)
b.equals(a) && b.equals(c) ==/==> a.equals(c)
Undirected edges are just fundamentally a different type to an S2Edge
and should be treated as such. Additionally they are only used privately
in one place and never using polymorphic behaviour.
