Edge-to-edge manga details view (#5613)

Browse Source 
* Prepare for edge-to-edge MangaController

* Fix derpy liftToScroll with our own implementation

* Edge-to-edge MangaController

Except when legacy blue theme is used.

* Save app bar lift state for controller backstack

* Fix expanded cover position after the view recycled

* Handle overlap changes when incognito mode disabled

* Tablet fixes

* Revert "Handle overlap changes when incognito mode disabled"

This reverts commit 1f492449

Breaks on rotation changes.

* Fix MangaController's swipe refresh position

* All controllers are now doing lift app bar on scroll by default

They are already doing that before so this pretty much just a cleanups.

* TachiyomiCoordinatorLayout: Support ViewPager for app bar lift state check

I'm willing to revert this if this minute detail solution is deemed too hacky xD

* Fix app bar not lifted when scrolled without fling

* Save app bar lift state across configuration changes

* Fix MangaController's swipe refresh position after configuration change

* TachiyomiCoordinatorLayout: Update ViewPager reference when controller is changed
