Man pages: refactor common options: --preserve-fds, -it

Three simple options shared among podman-create, exec, run.

I mostly went with the podman-run versions. For --tty, this
means that create and exec get the long stdout/stderr note.
(The example, though, remains only in podman-run). For -i,
mostly boldspace changes.

For --preserve-fds, podman-exec now has the "not with remote"
note (which it didn't until now)

 to run containers such as CRI-O, the last started container could be from either of those methods. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
