Cleans up/Refactors View.Subviews (#3962)
* Subview clean up * New Add/Remove event pattern * Using Logging * cleanup * Subview -> SubView * Test code cleanup. Killed many warnings. * Fix tznind feedback * Refactored AllViewTest helpers * Moved keyboard tests to parallel * Moved mouse tests to parallel * Moved view tests to parallel * Test code cleanup. Killed many warnings. * dupe test * Some mouse tests can't run in parallel because MouseGrabView * Made SpinnerView more testable * Moved more tests * SubViews to IReadOnlyCollection<View> * SubViews to IReadOnlyCollection<View> 2 * scrollbar tests * shortcut tests * Use InternalSubViews vs. _subviews * Nuked View.IsAdded. Added View.SuperViewChanged. * API doc updats * Unit Test tweak * Unit Test tweak
