Implement basic desktop app with chromium embeded framework (#2874)

* Remove tauri based desktop app

* Allow bzip-1.0.6 license

* Implement basic cef based desktop app

* Cleanup build setup

* Use wait until and execute cef loop more frequently

* Remove custom do browser work event

* Move WinitApp into its own module

* Cleanup event handling

* Cleanup + Scheudule cef message loop work

* Fix cpu overheating on idle: https://xkcd.com/1172/

* Use tracing crate for logging instead of println

* Rebase to main
