cbuildbot_stages.py: Refactoring of ReportStage.
This refactoring is a step toward removing the requirement of an
ArchiveStage in order to do anything in the ReportStage. It reduces the
usage of the ArchiveStage object during ReportStage.PerformStage() to
one place. A subsequent CL will complete the purge. This will allow
runs without an ArchiveStage (or board) to still do something in
ReportStage.
