Split API members into separate pages

[shimat]

Split DocFX managed-reference members into dedicated pages so large types such as Cv2 no longer render hundreds of method details in one document. Also filter OpenCvSharp.Internal.* from metadata and build input so NativeMethods and other implementation-only APIs do not inflate the site or search index, even when stale generated YAML is present locally.

The generated Cv2 class page falls from 1,289,216 bytes to 265,793 bytes, a 79.4% reduction, and links to 611 dedicated member pages. The complete generated site is 84.1 MiB and contains no Internal API pages.

Test plan

• Generate API metadata and the complete site with DocFX 2.78.5
• Build the final filtered site with 0 warnings and 0 errors
• Verify representative class, member, guide, xref, and search-index outputs
• Run git diff --check

Summary by CodeRabbit

• Documentation
  • Improved generated API documentation organization with separate pages for members.
  • Excluded internal APIs from published documentation.
  • Added filtering rules to keep internal implementation details out of the API reference.
