AnnotatedScrollBar doesn't dismiss tooltip on PointerLost

[karkarl]

Describe the bug

Tooltip for AnnotatedScrollBar is not dismissed properly if pointer is lost. I believe pointer handling for edge cases such as scenario below is needed.

Steps to reproduce the bug

1. Go to WinUI-Gallery -> AnnotatedScrollBar
2. Set window height to less than the AnnotatedScrollBar height
3. Drag AnnotatedScrollBar off window and see that the tooltip follows the pointer off screen
4. Let go of mouse drag and observe that the tooltip stays there until pointer re-enters and exits AnnotatedScrollBar
