Automerge: [clang-scan-deps] Remove unused OutputsPaths from FullDependencyConsumer (NFC) (#155523)

The OutputPaths field of FullDependencyConsumer is not used, and the
resulting TranslationUnitDeps has no corresponding field. This change
removes the unused member.

It was added in commit f978ea4, and this comment in the Differential
Revision suggests it was intended to be removed before landing:
