Tweaks to clarify tooltips from tool dropdown menus (#5123)

* Separate content from ToolbarItemTooltip, make simple and "rich" versions

* Add support for dropdown-arrow-only tooltip

* Add toolbar-wide hover timeouts and clears to switch between simple and rich tooltips

* Fix the dropdown arrow button hover styling now that they're separate

* Add missing doc links to rich toolbar tooltips

* A snapshot a day keeps the bugs away! 📷🐛 (OS: namespace-profile-ubuntu-8-cores)

* Re-run CI after snapshots

* fix codespell

* fmt
