Message:

Revisions: add a new filter for revisions to keep by post type.

Add a new wp_{$post_type}_revisions_to_keep filter that makes it convenient to filter the number of revisions created for a specific post type.

Overrides both the value of WP_POST_REVISIONS and the wp_revisions_to_keep filter.

Props dlh.
Fixes #51550.
