ViewRootImpl: Fix display install orientation query for transform hint

Apps did not get the correct transform hint when moving
between displays because the display install orientation
was not updated correctly. Fix by always querying the install
orientation instead of relying on the cached value.

Bug: 251360251
Test: move app between displays, rotate, check final buffer transforms
