Message:

Invalidate term query caches when setting or deleting term relationships.

Prior to 4.7, term relationships - as set by wp_set_object_terms() or
wp_remove_object_terms() - did not affect the term query cache. The
introduction of the 'object_ids' parameter in 4.7 means that the query
cache must be aware of object-term relationships. As such, the
'last_changed' incrementor is now invalidated when term relationships
are modified.

This bug only reared its head when delaying term counting, because term
counting performs its own term query cache invalidation.

Merges [40353] to the 4.7 branch.

Props mboynes.
Fixes #40306.
