When creating a framework for VisionOS, specifying "--dynamic" argument causes a build error. #25228
Description
System Information
OpenCV version: 4.9.0
Operating System / Platform: macOS ventura13.6.1
Compiler & compiler version: Cmake 3.28.1
Xcode version: 15.2
Detailed description
I get a build error when I specify the "--dynamic" argument to build_xcframework.py to build a dynamic framework for VisionOS.
If "--dynamic" argument is not specified, the build will succeed without problems. Or, if "--without=videoio" is specified, the build will also succeed without problems.

Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
