[troff]: Implement recursive node dumping (9/9).
Implement dumping of device extension node contents.
* src/roff/troff/request.h (class macro): Declare `json_dump()` member
function.
* src/roff/troff/node.cpp (device_extension_node::dump_properties): Call
member variable `mac`'s `json_dump()` member function.
* src/roff/troff/input.cpp (class macro_header): Declare `json_dump()`
member function.
(macro::json_dump): New member function calls `macro_header` `p`
member variable's `json_dump()` member function.
(macro_header::json_dump): New member function iterates though
`char_list` `cl` member variable's elements, calling
`json_encode_char()` on each one.
Changes `pline` request output as follows.
-{"type": "device_extension_node", "diversion level": 0, "is_special_node":
true, "tfont": "TR", "stroke_color": "default", "fill_color": "default"},
