Message:

Permalinks: Validate custom permalink structures.

Custom permalink structures require at least one valid structure tag, e.g. %postname%. If none is included, it would leave users with broken permalinks.
Let's make sure this won't happen by validating the permalink structure.

Adds unit tests.

Props rockwell15 for initial patch.
Fixes #35936.
