Man pages: refactor common options: --cidfile

There are two meanings: one writes a cidfile, the other reads.
Split into two .md files.

This can be reviewed with hack/markdown-preprocess-review .
The main differences you'll see are all in cidfile.read:

  1) I use the <<subcommand>> feature. This works nicely for
     kill, pause/unpause, and stop. It works less nicely for
     rm, because the man page will show "...and rm the container"
     (a human might prefer to see "REMOVE the container"). Given
     the benefit of this cleanup, I think this is a fine tradeoff.

  2) I choose to include the "multiple times" text even on man pages
     where it wasn't present before. I tested to make sure it works.

  3) The #### line I choose is IMHO the best one.

Minor differences:

  * I believe the "remove the container" text in podman-kill
    and podman-stop is a copy/paste error. This PR fixes it.

  * The only differences between the cidfile.write texts is
    the #### line (my version is best) and a final period.
