Maintain order in GlobalActions when rotating to/from seascape.

Previous code keeps the order wrt the hardware -- eg, power off is
always nearest the camera -- but this winds up being unintuitive.
Instead maintain reading order: power is always first, farthest
left/top.

Bug: 73910843, 73910843
Test: Manual in all 3 rotations.
