lib/bb/ui/crumbs/hobwidget: add HobButton widget for the primary action

The design uses a big, bold labelled, orange button for the primary action
on each dialogue. The HobButton implements this design as a reusable widget.

HobButton makes use of Pango Markup to use a relative size, x-large, for
the button text to ensure it's relative to the system configured font
sizes.
