Race condition while injecting ACTION_OUTSIDE

Race condition while injecting ACTION_OUTSIDE

In order to dismiss dialog in accessibility, we would also send
ACTION_OUTSIDE while performing ACTION_CLICK. However, the result
of performing ACTION_CLICK in AccessibilityInteractionClient may
be overwritten by the result of performing ACTION_OUTSIDE. This
causes that TouchExplorer may get incorrect result and follow-up
behavior is different.

Test: a11y CTS & unit tests
Test: After enabling Talkback, manually test on 'View Terms' page
      in ManagedProvisioning to check if the section heading can
      be expanded/collapsed by double tap.
