manual: introduce CMake logic for asciidoctor execution

Introduce new "manual", "manual-html" and "manual-pdf" make(1) targets
(the former depending on the latter). None of these targets are part of
"make all" by design, users decide whether to convert the manual text.
Execution will fail (fatally) in the absence of dependencies or tools.
