Support GIFs and animated stickers playback in notifications

[Dubzer]

It seems that starting with Android 12, it is possible to implement animated media playback in notifications: https://developer.android.com/about/versions/12/features#enriched_image_support_for_notifications

You can refer to home-assistant/android#4284 for working implementation (altough for some reason it states that it works only with Android 14+)
