[troff]: Implement recursive node dumping (5i/9).
* src/roff/troff/node.h (class vline_node): Specialize (override)
`dump_properties()` for this class.
* src/roff/troff/node.cpp (vline_node::dump_properties): New member
function reports value of `vunits` property.
Changes `pline` request output as follows.
-{"type": "vline_node", "diversion level": 0, "is_special_node": false},
+{"type": "vline_node", "diversion level": 0, "is_special_node": false,
"vunits": 15000},
