shiboken6: Improve detection of default/copy constructability

Add support for deleted functions. Extend the checks for default
constructability by checks for fields and base classes. Refactor the
check for copy constructability to recursively check on base
classes. Remove functionality for adding private copy constructors
which was apparently unused.
