Use higher QoS for WheelEvent and DisplayWasRefreshed IPCs since those are high priority. The UIProcess's main thread has high UserInteractive QoS but the IPC thread has a lower QoS by default. We cannot raise the QoS of the IPC thread without regressing some performance benchmarks since not all IPC is high priority.

This is causing WKWebView.PrepareForMoveToWindowThenClose API test to fail. I am investigating.
