Implements a DisplayList dumper.
This patch will iterate through the DisplayList after the reflow
is done and print its elements (as also any sub-lists associated
to a child node stacking context).
It adds a new CLI parameter to trigger the function to dump the display list
to console (i.e. servo --debug dump-display-list url).
Using both display list and flow tree information is helpful to debug
rendering issues.
