Fixes: MenuItem size fixes and missing separator with Gtk+

Task:     QTBUG-6522
RevBy:    thorbjorn
Details:

This fixes missing separator line in the Dust theme.

The patch also significantly improves the accuracy of menu item
size metrics by making use of gtk_widget_size_request to query
things like default heights.

- More accurate offset and size of separators
- Fixed item height of menu items using size_request
- Fixed vertical offset of label and check boxes
- Fixed clipping issue on last menu item
