Itemviews: add ItemIsUserTristate flag
ItemIsTristate is now again purely for enabling the automatic management
of the check state of QTreeWidgetItems, while ItemIsUserTristate is
separate from that and lets the user select the three states manually.
This restores the original behavior of ItemIsTristate for QTreeWidgetItems,
which got broken by letting the user cycle through the states too.
[ChangeLog][QtWidgets][QTreeWidget] Restored Qt 5.1 behavior of
QTreeWidgetItems with ItemIsTristate to enable automatic management
of the check state. User-editable tristate checkboxes are now enabled
by setting the new flag ItemIsUserTristate.
