Script loading: Fix regression after [43738].

After [43738], TinyMCE would be loaded earlier than before, which makes filters run at a different time relative to the loading of TinyMCE. Fix this by calling `wp_print_scripts` at the location where TinyMCE would previously be inserted as a `<script>` tag in the page.

Also, an TinyMCE translation related `<script>` that was mistakenly removed in [44115].

Props azaozz, omarreiss, swisspidy, atimmer.

Merges [43753], [43754] to trunk.

Fixes #45065.
