Subject: [PATCH] cgroup: Polish hierarchically aware protection docs a bit

I missed adding a section in `systemd.resource-control` about
DefaultMemoryMin in #12332.

Also, add a NEWS entry going over the general concept.

(cherry picked from commit acdb4b5236f38bbefbcc4a47fdbb9cd558b4b5c5)

Related: #1763435
