QTextLayout: Fix visual cursor movement in some cases

To guarantee proper positioning at the end of the last line in a
bidirectional text we have to insert the eol position into the
insertion points vector, accordingly to the visual ordering.
Detection of the last *logical* item in a *visual* line is unrelaed
to the text direction, it is simply `iterator.item == iterator.lastItem`.

[ChangeLog][QtGui][QTextLayout] Fixed visual cursor movement
in bidirectional text.
