Use case

#176860 is currently blocked because it adds a new android embedder dependency (androidx.exifinterface). Before the monorepo, it was expected this change would land and then a follow-up PR would update the lock files (see engine/src/flutter/tools/cipd/android_embedding_bundle/README.md).

However, since it's now a monorepo- the changes need to happen in the same PR. However,the script does not take into account local engine changes so running the script in the same PR does nothing.

Proposal

generate_gradle_lockfiles.dart needs to account for local engine changes when generating lockfiles.
