Combine null and non-null aggregatable report metrics in network sender

These reports have the same request format and report URL, so there is
no real benefit to measuring them separately. We have other metrics like
Conversions.AggregatableReport.ReportSendOutcome2 that can be used for
higher-level success/failure for non-null reports specifically.

OBSOLETE_HISTOGRAMS=Merged into same-named metrics without `Null` suffix
and with `2` suffix
