Auto merge of #8456 - ehuss:embedded-man, r=alexcrichton
Display embedded man pages for built-in commands.
This changes `cargo help COMMAND` to display the man page for the given command. `cargo COMMAND --help` continues to show the basic clap output.
The man pages are embedded in the executable in a compressed format. There's also a copy of the man pages in text format for platforms that do not have the `man` executable (like Windows).
It is unfortunate to check in more pre-generated files. I hope in the future that the usage of asciidoc can be replaced with something else (possibly a custom markdown-based solution).
