Add Sphinx cross-reference anchors for backends

Add explicit Sphinx file targets to OpenCV, GenTL and Basler backend docs and update camera_support.md to reference them via {ref}`... <file:...>` links. Clarify that GenTL requires vendor CTI files and remove the obsolete "Links to backend documentation" block, cleaning up backend listing and link targets.
