feat(command): Added command and hotkey binding for navigate to next and previous display set. (#3409)

* fix(command): Added command and hotkey binding for navigate to next and previous display set.

* Centralized the sorting (function) of display sets since at least three
areas sort display sets: hanging protocols, study/thumbnail browser and
updateViewportDisplaySet command.

* Renamed some methods for clarity.

* Scrolling active thumbnail into view for an updateViewportDisplaySet

* Added a null check.

* Added check to minimize thumbnail scrolling.
