Upgrade DrawerLayout to 1.2.0 and simplify code (#4412)
The main benefit of upgrading to version 1.2.0 of `DrawerLayout` is ~~to properly support **predictive back animations**: when initiating a back gesture on API 33+, the DrawerLayout will animate automatically~~ to handle back navigation automatically. The predictive back animation of the menu however depends on `NavigationView` which is not used in the project. In addition to the upgrade, simplify DrawerLayout integration: - Forward key events to the DrawerLayout so it can intercept them and close itself when needed. - Don't handle the DrawerLayout closing manually using the `OnBackPressedCallback` anymore. This is not necessary since the back event will now be intercepted by the DrawerLayout when needed before reaching the `OnBackPressedDispatcher`. - Remove legacy fix for DrawerLayout staying open after Activity recreation.
