Fix ShellTransitionTests on landscape devices

ShellTransitionTests uses the real primary display and
DisplayController, and the upside down rotation is 90 degrees on some
landscape devices. This CL changes it to a mock so we have better
control on its behavior.

Bug: 242207533
Test: atest ShellTransitionTests
