[troff]: Implement recursive node dumping (5n/9).
* src/roff/troff/node.h (class suppress_node): Specialize (override)
`dump_properties()` for this class.
* src/roff/troff/node.cpp (suppress_node::dump_properties): New member
function reports values of `is_on`, `emit_limits`, `filename` (if not
null), `position` (if not a null character), and `image_id`
properties.
"Suppress nodes" are some of groff's blacker magic, and are entangled
with grohtml. Given the following simple input document:
.EQ
x = 1
.EN
.pline
Hello suppress node world.
...processed with `groff -e -Thtml` (and application of `sort -u` to
stderr), this commit changes `pline` request output as follows.
