Always return Granted for Read-Write Storage permissions on Android

[jfversluis]

Description of Change

The android.permission.READ_EXTERNAL_STORAGE and android.permission.WRITE_EXTERNAL_STORAGE permissions are no longer available on Android 13 (API 33) and up. This PR changes the current .NET MAUI implementation to not change anything for < API 33, and always returns granted for API 33+.

If you want to access specific media files, you now need to request specific permissions for that. This PR don't implement those yet. For the time being you can implement those manually if you need them, following this documentation here: https://learn.microsoft.com/dotnet/maui/platform-integration/appmodel/permissions?tabs=android#extending-permissions.

Issues Fixed

Fixes #14729

I know this has new APIs but it seems that this is important/blocking enough to bring this back to .NET 8 servicing?

Will there be an expectation to support mapping to the new more granular Android permission?

If your app targets Android 12 or lower, you must request the READ_EXTERNAL_STORAGE permission. If your app targets Android 13 or higher and needs access to files that other apps have created, you must request one or more of the following granular permissions instead of the READ_EXTERNAL_STORAGE permission:

• READ_MEDIA_IMAGES
• READ_MEDIA_VIDEO
• READ_MEDIA_AUDIO

Yeah as mentioned in the opening post, I think people should be able to manage on their own by implementing these permissions if they need them right now while we get to it. There is this issue to track the implementation of the new media permissions: #12857. This just focusses on unblocking the missing READ_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions for API 33+
