Ensure that "ThreadController active" events aren't included in our breakdown of flow events. These are special ones which track the ThreadController being active, and thus span multiple tasks. We currently assume the top level parent is just the current task running, but "ThreadController active" can span multiple tasks and thus should be removed. Update scroll_jank_mojo_simple_watcher.py to prevent regression (this test failed after modification of the .py and before the scroll_flow_event.sql change). Also update the metric to handle the new FINISHED_SWAP_BUFFERS to end, since the end will be on the threadpool we aren't interested in the tasks which block the threadpool from running.
