This commit does the following:
- Splits the podman-systemd.unit.5.md into multiple files - one for each
quadlet file type, podman-quadlet.7.md for general quadlet information
and podman-quadlet-basic-usage.7.md for quadlet examples.
- Removes the original podman-systemd.unit.5.md file.
- Adds support for jinja2 templating language in the markdown_preprocess.
- Uses jinja2 in options/*.md to use the single .md file for both podman
subcommands man-pages and quadlet man-pages. This deduplicates
the Quadlet man-pages a lot.
- Adds new `@@option quadlet:source.md` preprocess command to import
such .md files from options directory.

Document the special *host-gateway* flag introduced with #19152, mention the special `host.containers.internal` and `host.docker.internal` hostnames, and clarify the option's usage in general.

In each options/foo.md, keep a list of where the option is used.
This will be valuable to anyone making future edits, and to
those reviewing those edits.
This may be a controversial commit, because those crossref lists
are autogenerated as a side effect of the script that reads them.
It definitely violates POLA. And one day, some kind person will
reconcile (e.g.) --label, using it in more man pages, and maybe
forget to git-commit the rewritten file, and CI will fail.
I think this is a tough tradeoff, but worth doing. Without this,
it's much too easy for someone to change an option file in a way
that renders it inapplicable/misleading for some podman commands.
