TextBoxWidget: fix some truncation ellipsis issues

Ellipsis was sometimes not displayed when text is right aligned,
because width was not updated with ellipsis size.
bump base/xtext: fix truncation ellipsis position in bidi text
so it stays nearer to previous logical order char, instead of
sometimes being thrown away to start or end of line.
