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.
