[Backport] Security bug 1423360
Manual backport of patch originally reviewed on
https://chromium-review.googlesource.com/c/chromium/src/+/4455016:
Fix ScopedObservation UaF in BubbleDialogDelegate::AnchorWidgetObserver
A ScopedObservation can outlive the aura::Window it observes, leading to
a use-after-free error in ~ScopedObservation(). The problem occurs in
BubbleDialogDelegate::AnchorWidgetObserver. This fix listens for
OnWindowDestroying() and resets the observation to prevent the UaF.
