ExperimentalEventHandler: add a shutdown flag We've observed hangs of Bazel on shutdown with thread stacks indicating that the cli-update-thread does not exit properly. We don't know why this is happening, and have no easy way to reproduce. My best guess is that the interrupt is swallowed somewhere, although I was unable to pinpoint a specific place where that could happen. As a defensive mechanism, this change adds a boolean flag that signals to the CLI thread to shutdown in case the interrupt signal gets lost. This also helps with a potential race between startUpdateThread and stopUpdateThread. Possible fix for #8432. PiperOrigin-RevId: 249612495
