When planning a caching build with bridging header, the consumer of the pre-compiled bridging header needs to know the cache key for the bridging header in order to construct the correct build command, which requires visibility to the job that creates PCH. Fix the incremental planning for bridging header users so those job can be correctly constructed even the bridging header job is skipped for the incremental build. rdar://118143215
