+lighthouse folks
+traceviewer folks because of TOP_LEVEL_TASK_TITLES in https://cs.chromium.org/chromium/src/third_party/catapult/tracing/tracing/extras/chrome/event_finder_utils.html?type=cs&q=ThreadControllerImpl::DoWork&sq=package:chromium&g=0&l=25-34 


The DoWork trace event is now under the 'sequence_manager' category and no longer has the same meaning.
The new "ThreadControllerImpl::RunTask" event (on 'toplevel') reflects the same uninterruptible task used for our metric purposes.


Also, altimin points out over IM: "The RunTask scope is refined and it should be slightly smaller than of the old DoWork."

FYI we'll have to fix this in Lighthouse, roll it into DevTools audits panel, and also merge back to m69.
Not sure if it's important enough for traceviewer for them to fix and merge, too.

Fix top level scheduler task title

The top level scheduler task was renamed, so changing all refs
to that name. The old TaskQueueManager::DoWork event now has
category 'sequence_manager', and has different semantics. To
maintain backwards compatibility, we still consider
TaskQueueManager::DoWork events with 'toplevel' category to be
scheduler top level tasks.

This also changes total EQT to use scheduler task. This was a
case that was missed while fixing  crbug.com/832651 .
