Enhance build scripts and documentation for MediaPipe GPU Wheel

- Updated `build-multiple.sh` to allow continued builds for other Python versions even if one fails, and added reporting for failed builds.
- Improved `build.sh` to ensure log files are created and output is properly logged.
- Enhanced `stop-builds.sh` to include comprehensive Docker cleanup, removing unused images and build cache.
- Updated `README.md` to clarify the functionality of `stop-builds.sh` with additional details on Docker cleanup processes.
- Added a note on production readiness issues in `PRODUCTION_READINESS_ISSUES.md` to emphasize the need for addressing memory leaks and GPU context issues.
