Message:

Taxonomy: Bypass clearing taxonomy hierarchy for non-hierarchical taxonomies.

Modifies clean_taxonomy_cache() to bypass attempting to delete the {$taxonomy}_children option for non-hierarchical taxonomies, such as tags.

This removes a needless database query within delete_option() to determine if the {$taxonomy}_children option is set. It isn't.

Props: chouby, mukesh27, rollybueno, sabernhardt, shailu25, spacedmonkey, westonruter.
Fixes #64090.
