Fold the standalone 'Validate cache with cache-dependency-path option'
workflow into e2e-cache.yml and delete the separate file. The three
gradle1-save/gradle1-restore/gradle2-restore jobs are copied verbatim,
preserving their matrix, cache-dependency-path inputs, and needs
relationships. No change in test coverage.
