[opencv4] feat: pass CUDA_ARCHITECTURES

[air-hand]

Pass CUDA_ARCHITECTURES through as CMAKE_CUDA_ARCHITECTURES when building opencv4 with the cuda feature.

This lets users configure CUDA architectures from their triplet instead of falling back to OpenCV's default CUDA architecture selection, which can trigger unnecessary CUDA compilation.

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Exactly one version is added in each modified versions file.

This variable lacks documentation, is this supposed to be a well-known environment variable? Otherwise, we may want to add a comment for users of the port to know this is a triplet variable.

Thanks for your review.

I used CUDA_ARCHITECTURES here to match the existing darknet port pattern.
The name also lines up with CMake's CUDA_ARCHITECTURES target property.

Sorry, I missed updating the version database.
