REST API, Posts: Add a hook to fire once a post, its terms and meta update.

Browse Source 
Introduces the action `wp_after_insert_post` inside a wrapper function of the same name. This hook allows plugin developers to access a posts full data (including its terms and meta data) regardless of the workflow used to save it.

A new parameter is introduced to `wp_insert_post()` to indicate whether the hook should be fired within the function call or will be fired afterward.

Fixes #45114.
