For ANRs, reduce EXPIRED_REPORT_TIME_MS to 10s

Browse Source 
After 10s, the state of other processes is likely to not be useful anyway to debug the ANR.

If there is already a delay on the queue, not dump all the proceses will also help to recover more quickly so that future ANR snapshots are more accurate (smaller latency)
