Complete vnd7050aj module integration

- Move DTS binding from project root to module folder
- Update module.yml to use correct dts_root path
- Restructure module for better organization and portability
- All module files now self-contained in modules/vnd7050aj/

Module structure:
- CMakeLists.txt: Uses zephyr_library for proper integration
- Kconfig: Module configuration options
- dts/bindings/: Device tree binding definitions
- include/: Public header files
- src/: Module source code
- zephyr/module.yml: Module discovery and configuration

Build verified successful on both x86 and ARM targets.
