Magnetic Swipe Refactor to better handle edge cases.

For cases in which magnetic interaction ends during magnetic animations,
we make sure that the corresponding magnetic and external animations are
cancelled or coordinate to avoid flickering behaviors. This involves
cases when notifications are swiped away by the system when the magnetic
behavior is active (e.g., clicking "clear all")

Test: MagneticRowManagerImplTest
Test: manual. Verified correct animations in edge cases above.
