Upgrade DrawerLayout to 1.2.0 and simplify code

[cbeyls]

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.

That would be super cool but it doesn't do anything here (Api 34 emulator, predictive back enabled, this branch) 🙁

Indeed it turns out the DrawerLayout properly handles the back gesture but the animation part is handled by NavigationView from the Material Components library. Tusky uses the MaterialDrawer library from Mike Penz instead, which doesn't support this feature (even in the newest version apparently).

It's still worth the change for the simpler code I think.

yes, definitely
