Swaps the value of @first and @second if @second comes before
@first in the buffer.
That is, ensures that @first and @second are in sequence.
Most text buffer functions that take a range call this
automatically on your behalf, so there’s no real reason to
call it yourself in those cases. There are some exceptions,
such as [method@Gtk.TextIter.in_range], that expect a
pre-sorted range.
