SERVER-39356 Refactor speculative majority read data structures and methods to use timestamps instead of optimes

This patch refactors the SpeculativeMajorityReadInfo class and the awaitOpTimeCommitted method to accept timestamps as input instead of optimes. When waiting for an operation to majority commit, term information, which is included in optimes, isn't necessary, since timestamps are totally ordered within a local oplog, and so are safely comparable. It is, for example, safe to determine if a local oplog entry is majority committed by checking if its timestamp is less than that node's local view of the majority commit point. This patch should not introduce any observable functional changes.
