docs: add container bundling and vdkr/vpdmn documentation

Add comprehensive documentation for the container cross-install system:

- Choosing between BUNDLED_CONTAINERS and container-bundle packages
- Decision guide table for selecting the right approach
- Component relationships (app recipe -> container image -> bundle)
- BUNDLED_CONTAINERS format and examples
- container-bundle.bbclass usage
- Container autostart configuration
- vdkr/vpdmn virtual container runtime usage
- Architecture overview and how it works
- Testing instructions

This provides a single reference for users wanting to bundle containers
into Yocto images at build time.
