WebKit currently only listens for thermal state changes on visionOS. We should also do this on iOS. The main mitigation here is increasing the frequency of setInterval callouts. In the future, we may enable more aggressive mitigations if they don't cause impacts on benchmarks (see the disabled RespondToThermalPressureAggressively preference).
