    Add support for resetting library state in response to CANCEL events and clearing of selection.
   
    Sepcifically:
    - BandSelectionHelper#reset
    - GestureSelectionHelper#reset
    - Clearing Selection in tracker.
    - Reset the OperationMonitor.
    - Connect explicit clearSelection (as clients call from back button) to reset.
   
    GestureDetector is already listening for CANCEL events, cleans up its own state internally.
   
    Related cleanups:
    - Add onSelectionCleared support to SelectionObserver class.
    - Guard all runtime state checking behind DEBUG bit (mis-configuration still throws).
    - Deprecate support for setting gesture/pointer tooltypes.
    - Define more events in TestEvents.
    - Cleanup naming and consoliate some tests in BandSelectionHelperTest.
    - Remove support POINTER_UP in BandSelectionHelper...POINTER_UP is for secondary pointer
      devices only, which is outside of the domain of BandSelectionHelper.
   
    BUG: 137460699
    Test: Passing, added new test related to reset behavior.
