More bottom sheet improvements (#5183)

* Edge-to-edge bottom sheet when possible

* ReaderSettingsSheet: Animate background dim changes

* Adjust modal bottom sheet in-out animation

* Use public method to get bottom sheet behavior

* Set bottom sheet peek size to 50% screen height

The current auto peek height gives too low value on landscape orientation

* Set bottom sheet navigation bar scrim when needed
