Add support for predictive back gesture

[connyduck]

About this issue

MaterialDrawer should have the same or a similar predictive back animation as com.google.android.material.navigation.NavigationView has. I attached a video so you can see what I mean:

More information on predictive back: https://developer.android.com/guide/navigation/custom-back/predictive-back-gesture

Since Android 15, predictive back is no longer optional, and users expect the app to do something when they start the back gesture, but unfortunately the MaterialDrawer just stays in place.
