Subject: [PATCH] Posts, Post Types: Allow bypassing of term classes in
 `get_post_class()`.

Introduces the filter `wp_post_class_taxonomies` to allow developers to bypass the generation of term based classes with the `get_post_class()` function.

Developers can use this filter to reduce the number of taxonomies for which classes term classes are generated. This can improve performance on sites with a large number of custom taxonomies.

Fixes #37114.
