Xi Ge 8225b522d0 swift-api-digester: de-duplicate protocol conformance entries in the Json output ...

For some unclear reasons, calling getAllConformances on Int.Words and
UInt.Words returns duplicate entries for conforming to RandomAccessCollection.
Since this isn't the case for swift-5.1-branch, we saw false positives shown
in rdar://49568079.

This patch fixes the ABI/API checker by de-duplicate results collected from
getAllConformances.
