Add OverviewDesktop test to verify carousel behavior on swipe up

This CL updates a test to verify the behaviour while swiping up from a fullscreen app to Overview and checking if that TaskView is between DesktopTasks (right side) and Grid Tasks (left side).
The test adds the following validations:
- Launches adjacent task while DesktopTask is at the center of the screen
- Swipe up from a fullscreen app to Overview to validate whether the task is between other tasks and desktop tasks.
- Fling back to DesktopTask to dismiss the adjacent focused task
