Subject: [PATCH] Toolbar: Load toolbar in `wp_body_open` when available.

For accessibility, the visual appearance and source order should match. Moving the toolbar to load in the new hook `wp_body_open` (5.2) fixes a long-standing source order problem.

Props jankimoradiya, afercia, SergeyBiryukov, audrasjb, ocean90, xkon, dinhtungdu.
Fixes #47053.
