drivers: video: add support for Renesas RA CEU driver 



Add support for the Renesas RA Capture Engine Unit (CEU),
including driver source files, Kconfig options, and DTS bindings.

- Add initial implementation of the RA CEU driver
- Add dedicated Kconfig and CMake integration
- Provide Devicetree bindings for the RA CEU
- Update module Kconfig to include the new driver

This enables image capture functionality using the CEU peripheral
on Renesas RA series MCUs.
