Improve distro layer CI workflow with proper Yocto environment setup

🔧 Enhanced CI Validation:
- Add proper Yocto environment initialization with oe-init-build-env
- Add BitBake environment testing before running yocto-check-layer
- Add basic recipe parsing test to verify environment
- Improve error handling and analysis robustness
- Make workflow continue for debugging even with validation issues
- Add detailed logging and error counting

This addresses the yocto-check-layer failures by ensuring the
BitBake environment is properly initialized before validation
and provides better debugging information when issues occur.
