        Build the parts used in the last summary stats line.

        The summary stats line is the line shown at the end, "=== 12 passed, 2 errors in Xs===".

        This function builds a list of the "parts" that make up for the text in that line, in
        the example above it would be::

        That last dict for each line is a "markup dictionary", used by TerminalWriter to
        color output.

        The final color of the line is also determined by this function, and is the second
        element of the returned tuple.
