Message:

Taxonomy: add a new 'terms_pre_query' filter to short circuit WP_Term_Query 'get_terms' queries.

Add a new terms_pre_query filter which returns null by default. Return a non-null value to bypass WordPress's default get_terms queries.

Props jarocks, boonebgorges, spacedmonkey.
Fixes #41246.
