DuckStation: Failed to start ACTION_OPEN_DOCUMENT_TREE intent, solved for Android TV 11+ & Google TV

Since the release of Android TV 11, including Google TV, apps are required to use the Scoped Storage API, causing many emulator apps to break as they need to access files from storage. For instance, the DuckStation emulator doesn't work on most Android TV and Google TV devices because they lack a Scoped Storage Access Framework (SAF) file picker. Fortunately, there's now a workaround using S2X's file picker interface. This enables DuckStation to open BIOS or game files from TV storage. Let's explore how to do this.

Works on: MI TV STICK, MI BOX S GEN2, Chromecast with Google TV and other Android TV 11+ and Google TV devices.
