Create a new Git subcommand called repo-info. `git repo-info` will query
metadata from the current repository and outputs it as JSON or plaintext.

Also add entries for this new command in:

- the build files (Makefile and meson.build)
- builtin.h
- git.c
- .gitignore

In option parsing, use PARSE_OPT_KEEP_UNKNOWN_OPT to allow the users
specify after the flags the information that they want to retrieve.

Something I mentioned in the previous review, but hasn't been addressed
is the addition of documentation for the new command. With each patch
modifying the command, it would be also nice to add the respective
documentation.
