PySide2: Prepare for Qt 6

- Change QBasicTimer to be an object type since its copy constructor
  and assignment were deleted in Qt 6. It probably was never
  intended to be a value type.
- Remove the hash function of QItemSelectionRange which
  according to code comment is a dummy to get
  QItemSelectionRange::toSet() compiled with MSVC. There is no need
  for it to have it in Python
- Adapt the underlying string types for QString conversion
