feat: add CEF support

[lucasfernog]

note: requires cargo install --git https://github.com/tauri-apps/tauri --branch feat/cef tauri-cli to be ran first as it relies on unreleased changes on Tauri's feat/cef branch

I noticed it doesn't really open the main window on the first run, I had to run it with wry first (probably a missing CEF event?)
