Message:

Posts, Post Types: Set post filter in update_post_cache().

Ensure the post cache is primed with raw sanitized data. This resolves an inconsistency between how posts retrieved via get_post() vs WP_Query are cached.

This prevents sanitize_post( $post, 'raw' ) being run multiple times on a cached post. This can happen over 20 times per post on some page loads so avoiding this will provide a noticeable performance boost.

Props Cybr, SergeyBiryukov, peterwilsoncc, hellofromTonya, costdev.
Fixes #50567.
