RevWalk: Store RevFilter metrics within a new RevFilterStats class

TreeRevFilter is an internally created RevFilter by StartGenerator when
the invoker wants to filter commits by a TreeFilter. The
ChangedPathsFilter metrics stored within TreeRevFilter are impossible
for the invoker to get since the invoker does not hold any reference to
the TreeRevFilter.

Since all RevFilters have access to RevWalk via the default Include()
method, creating a RevFilterStats as a data container within Revwalk to
store and provide access to any metrics generated by RevFilters.
