 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.
