Revert "Fix scrolling in the  `Drawer` and `NavigationDrawer` triggers AppBar's scrolledUnderElevation" (#124226)

Revert "Fix scrolling in the  `Drawer` and `NavigationDrawer` triggers AppBar's scrolledUnderElevation"

In #122336 we migrated the principal class from NSApplication to
FlutterApplication in the app Info.plist. We removed the need for
FlutterApplication in https://github.com/flutter/engine/pull/40929. This
reverses the migration for anyone who previously upgraded on the Flutter
master branch.
