feat: Add traffic light inset

[FabianLars]

fixes #1056

I really wanted to fix this in tao or maybe in tauri but i just wasn't able to fix it in tao and in tauri it would have resulted in much more code (overwriting delegates and shit, see tauri-apps/tauri#4789

Also the options seemed to conflict with with_decoration in Tao. I think we should mention that the app would panic if the title bar doesn't exist.

Another question is whether the setting works on multiple monitors with different DPI?
It looks good on different DPI

Oh yes, absolutely. It requires a hidden title setting (which also means decorations are required). I meant to copy paste the electron docs document this but forgot about it because of another doc change.

Hi, I am the original guy who tried to work on this. I have no idea what you did to fix this but I thank you deeply from my heart. I just couldn't look at this mess any longer without becoming anxious 😅

More importantly: I have lost track of this whole thing. Does my my kind of broken inset method still exist in Tao? If yes we should probably remove it right?

[FabianLars]

I couldn't have done it without you 🫂

And no, we still need the Tao method. The method is also no broken (after all i use the very same impl here). It's still needed if the webview is injected via build_as_child (for multiwebview support for example). We probablyyy could overwrite this here as well, but imo windowing stuff should stay in the windowing library as much as possible.
Additionally, we still need the Tao implementation for what i fixed here as well, otherwise we would end up with the same flicker (but kinda in the opposite way). At least it did in my earlier tests.
