Message:

Taxonomy: Introduce 'cache_results' parameter to WP_Term_Query for bypassing query caching.

Incorporating a new 'cache_results' parameter into the WP_Term_Query class, this commit empowers developers with the ability to bypass query caches, explicitly triggering database queries when needed. This brings the WP_Term_Query class inline with WP_Query and WP_User_Query that already have a 'cache_results' parameter.

Update the term_exists function to use this new parameter, so the term query caches are not used while importing.

Props dlh, spacedmonkey, peterwilsoncc.
Fixes #52710.
