PHP Notice: edit_form_advanced is deprecated since version 5.0.0!

[Chouby]

This notice is fired in the block editor due to:

add_action( 'edit_form_advanced', array( $this, 'maybe_run_ajax_cache' ) );

in class-wp-embed.php.

The issue has already been reported in #45341, but as this ticket doesn't focus on the notice but on different javascript errors, I thought it would be good to open a separate ticket.

Tested with 5.0-RC2-43958

I'm milestoning this to 5.0.1 due to the fact that the release is scheduled for tomorrow. If @pento wants to disagree and include it in 5.0.0, I wouldn't object.

Props pento.
