Add HdySearchBar

This is similar to GtkSearchBar except it allows the central widget
(typically a GtkEntry) to fill all the available space. This is needed
to manage an entry's width via a HdyColumn, letting the entry (and by
extention the search bar) have a limited maximum width while allowing it
to shrink to accomodate smaller windows.
