Doc: Fix multiple C++ documentation issues

    - Remove multiple \namespace commands for namespace Qt3D. QDoc in 5.5
      is now able to collate namespace members from multiple modules.
    - Mark 'Q...Private' classes and functions taking private arguments as
      \internal
    - Use correct \qtvariable for Qt 3D Core and Render
    - Add src/plugins directory to Qt 3D Core documentation build to
      correctly generate Assimp-related documentation.
    - Ensure documentation for C++ properties is visible by
      using the \property command instead of documenting the
      setter/getter functions.
    - Add export and logging macros to qdoc ignore directives
    - Remove unnecessary use of \fn command
    - Language and styling fixes
