camera: add generic NHX and CAMX helper updates

Update camera helpers to better support NHX validation across targets.

Changes include:
- board-aware camera module selection from DT data
- generic CAMERA_ICP firmware discovery under /lib/firmware/qcom
- package detection for both opkg and dnf/rpm based images
- cam-server logging helpers for status and stdout capture
- NHX dump size helper built on shared file size detection
