[metrics] Add thread creation spam stats to android_task_names First added an ANDROID_THREAD_CREATION_SPAM stdlib function to find stats of rapidly created threads. To support finding thread names where only some suffix changes, e.g Thread-123, we aggreate the stats per process per thread prefix. We currently use a STR_SPLIT workaround to find prefixes by splitting thread names by some common delimiters. When we have perfetto REGEXP support, we can replace this with a more robust solution.
