formatter: map -Tjson(...) and -Tcbor(...) to templater

Even though custom JSON output could be generated by using
--config template.json="{dict(...)|json}" ..., doing that is tedious because
of the trailing comma handling.

This patch introduces special syntax for JSON/CBOR formats. -Tjson(...) is
translated to template as if function-style template definition were
supported:

  [templates]
  json(...) = "{dict(...)|json}"
  json(...):docheader = "[\n "
  json(...):docfooter = "\n]\n"
  json(...):separator = ",\n "
