Remove DifferentialRevisionListData

Summary: Ref T603. This is a very old, very bad version of DifferentialRevisionQuery. I want to modernize only the latter. Express the remaining callsite of the former in terms of DifferentialRevisionQuery.

Test Plan: Executed all four modes of differential.find.
