Taxonomy: Improve performance of term recounting database queries.

When modifying terms assigned to an object, replace full term recounts with incrementing/decrementing the count as appropriate. This provides a significant performance boost on sites with a high number of term/object relationships and/or posts.

Introduces the functions `wp_increment_term_count()`, `wp_decrement_term_count()`, `wp_modify_term_count_by()` and `wp_modify_term_count_by_now()` for updating the term count.

Introduces the function `_wp_prevent_term_counting()` for preventing double counting on posts that are about to transition.

Adds the parameter `update_count_by_callback` to `register_taxonomy()` to allow developers to use a custom callback for incrementing or decrementing a term count.

Props boonebgorges, davidbaumwald, hellofromTonya, johnbillion, lcyh78, mattoperry, peterwilsoncc, rebasaurus, whyisjake.
Fixes #40351.
