Introduced the visual stability manager

Notifications used to roam around and reorder whenever
they wished. Those little beasts must be tamed, hence

dictates the terms of their interplay.

Test: manual: add heads-up and see if they correctly appear
Test: runtest -x packages/SystemUI/tests/src/com/android/systemui/notification/VisualStabilityManagerTest.java
