Auto-dismiss ANR dialog during element waits

CI emulator occasionally raises a system "isn't responding" dialog
(e.g. on Quickstep/launcher) under CPU pressure, which sits on top of
the app and blocks every element lookup until dismissed, causing
element-wait timeouts even though the underlying screen rendered fine.
