Skip title, description and exceprt sanitization and let WP handle it

Should simulate the same behavior from WP admin, so just need to skip
extra sanitization, so WP can handle it while salving with
`wp_insert_post()` and `wp_update_post()` where will check for
`unfiltered_html` capability.

WP core already did something like it, but on REST API: https://core.trac.wordpress.org/ticket/38609

Fixes #16195
