Track unread streams in SimpleCache.CheckCRCResult
We're seeing very high rates of reporting (~37%) of "Was never read to
end" from SimpleCache.CheckCRCResult. This is almost certainly from
unread metadata streams (~33% of streams) and HTTP payloads being
unread because the headers force an update (CantConditionalize = 4% of
requests, and Updated = 1% of requests).
By distinguishing never read streams from partially read streams, we
can be more sure about how often we risk providing bad data to
clients.
