Building on #2913, we can decouple help generation from help formatting, which would allow us to reuse it for manpage generation or for code-gen of help output to avoid doing help generation at runtime, allowing users to reduce bloat.
Describe the solution you'd like
Refactor clap_help to accept an impl HelpBuilder which we can tell pass it parts of the help output and the impl is responsible for formatting for the target (terminal, man page, pre-proc for code-gen, etc)
