fix failure of CompatChangeTests

For our old foldable device that launching with android R, when test the case in foldable state, the physical size is 880x2640. It is hard for us to modify the physical size, which may cause many applications adaptable problems. So the value of ACTIVITY_LARGE_MIN_ASPECT_RATIO(3.0) is not applicable to old devices, we need to increase ACTIVITY_LARGE_MIN_ASPECT_RATIO to 4.
