Add Docker build scripts for OpenCV.js with enhanced configuration

- Created a new Windows batch script `build_w_docker.bat` for building OpenCV.js using Docker, including user permissions handling and output directory management.
- Updated the existing `build_w_docker.sh` script to improve error handling and ensure proper directory permissions, while aligning the Docker image version with the new batch script.
- Modified the OpenCV submodule to update to the latest commit.
