Subject: BaseTools/Scripts/GetMaintainer: Handle reviewer only case

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4593

If a package only has reviewers and no maintainers, then also
return the <default> maintainers.

In order to detect this case, get_maintainers() is updated to
return maintainers, reviews, and lists separately instead of
a single merged list.  This also allows this module to be used
by other scripts that need to distinguish between maintainers,
reviewers, and lists.
