I assume you just mean tmp and not tmpfs at the end there?
All of those file systems are handled internally as "API" filesystems
inside systemd. You do not need fstab entries or .mount units for the
above - they should all "Just Work"(tm)
But to answer the question theoretically: you would need one unit per
mount point. If you want to keep things in one file, just keep them in
fstab as before.

systemd doesn't support a /etc/mtab which is a statically managed file.
It basically requires that /etc/mtab is a symlink to /proc/mounts which
is dynamically updated from the kernel.
So there is no option for this because there is no need.
