Fix wrong divider position after rotation
Ratating from 270 -> 0 -> 90 keeps wrong "mNonDecorInsets" in the
DisplayLayout of split screen due to not updating insetsState when
insetsChanged. Updates to stop house keeping DisplayLayout separately in
split screen component by fetching it from DisplayController directly.

Test: manual by issue steps:
1) Launch apps to enter split-screen mode
2) Rotate to 270
3) Rotate to 0
4) Rotate to 90
5) Expect the position of split-tasks is right
