Flush SequenceWorkerPool tasks after each test. Applies to unit_test, interactive_ui test, browser_tests... pretty much all gtest based content library test harnesses are affected.
The CL changes semantics and implementation of the existing FlushForTesting method (which wasn't suitable for this usage).
* The old method would wait for delayed tasks prior to continuing, the new method
will not run them but will delete them prior to continuing.
* The old method would deadlock if called after Shutdown had been called, the new method returns immediately in that case.
A few SWP unittests relied on the waiting for delayed task completion behavior. Those have been modified to explicitly wait thru other means.
