[WIP] [tvOS] Sign-In Flow - User Auto Time-Out

[chickdan]

Early efforts in implementing https://github.com/ViacomInc/TVOSPicker mentioned in #1419

I think it's getting close but I found a bug with the .blurredFullScreenCover(isPresented:) view modifier. In both SignOutIntervalSection and VideoPlayerSettingsView the presented blurred overlay immediately dismisses itself with the following error:

Attempt to present <_TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView_: 0x108071000> on <_TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView_: 0x107875800> (from <_TtGC7SwiftUI19UIHostingControllerVVS_P10$1afce442c21BridgedNavigationView8RootView_: 0x1078e5000>) while a presentation is in progress.

In one of the other PR that I have open, I wanted to do something similar to the blurred full screen and was running into a similar error. So, I ended up adding the view to the coordinator and calling it with .fullScreen instead of .push or .modal.

I was basing it off of the item overview, which does this same thing:

I ended up doing it at the same way for both my open playlist and filters PR. It's kind of a pain and adds an extra step, but it should work for getting you past that issue! I did it here with the filter:
