Revisions: Clean up _wp_post_revision_fields():

Browse Source 
* Move the array processing to a new function, `_wp_post_revision_data()`.
* Make both functions accept a post array or a `WP_Post` object. 
* Always apply the `_wp_post_revision_fields` filter and pass the post data to it.

Fixes #13382.
