Block Editor: Fix the TinyMCE `wordpress` plugin to handle hiding/showing of toolbars in the classic block. Change the classic block toolbar to use the (now fixed) `wp_adv` button.

Props azaozz.
Merges [43889] and [43890] to trunk.
Fixes #45264.
Built from https://develop.svn.wordpress.org/trunk@44247
