Improvements to ActivityManagerService stack dumping
- Deduplicate code in DumpStackFileObserver, ensure consistent behavior at addition use site
- Fix bug in DumpStackFileObserver where closed state was not reset
- Align TRACE_DUMP_TIMEOUT_MS with frameworks/native/cmds/dumpstate/utils.cpp
- Fallback to Debug.dumpNativeBacktraceToFileTimeout on timeout
- Share timeout constant with other Debug.dumpNativeBacktraceToFileTimeout caller
Test: Insert 1s sleep in system/bt/btif/src/bluetooth.cc is_profile to trigger ANR
Test: Insert hang into art/runtime/signal_catcher.cc after "reacting to signal"
