docs: Returns the information about a set breakpoint.
  
          Note:
            Either ``handle`` or ``index`` can be specified.  If the ``index``
            is not provided, the ``handle`` must be set, and vice-versa.  If
            both ``index`` and ``handle`` are provided, the ``index`` overrides
            the provided ``handle``.
  
          Args:
            self (JLink): the ``JLink`` instance
            handle (int): option handle of a valid breakpoint
            index (int): optional index of the breakpoint.
  
          Returns:
            An instance of ``JLinkBreakpointInfo`` specifying information about
            the breakpoint.
  
          Raises:
            JLinkException: on error.
            ValueError: if both the handle and index are invalid.
