I'd prefer using TaskType::PerformanceTimeline (just in case).

With which LocalFrame/Document/ExecutionContext/ScriptState? I could pass in the
ScriptState from PerformanceBaseTest::initialize here (though it seems odd to
simultaneously have TestPerformanceBase::getExecutionContext return nullptr).

   ~TestPerformanceBase() {}
 
   ExecutionContext* getExecutionContext() const override { return nullptr; }
 
   int numActiveObservers() { return m_activeObservers.size(); }
 
   int numObservers() { return m_observers.size(); }
 
   bool hasPerformanceObserverFor(PerformanceEntry::EntryType entryType) {
     return hasObserverFor(entryType);
