[troff]: Implement recursive node dumping (5h/9).
* src/roff/troff/node.h (class hline_node): Specialize (override)
`dump_properties()` for this class.
* src/roff/troff/node.cpp (hline_node::dump_properties): New member
function reports value of `hunits` property.
Changes `pline` request output as follows.
-{"type": "hline_node", "diversion level": 0, "is_special_node": false},
+{"type": "hline_node", "diversion level": 0, "is_special_node": false,
"hunits": 144},
