[iOS] CheckedPtr crash under [WebThermalMitigationObserver
thermalStateDidChange]
https://bugs.webkit.org/show_bug.cgi?id=313091
rdar://170616981
Reviewed by Ryosuke Niwa.
Make ThermalMitigationNotifier ref-counted instead of CanMakeCheckedPtr
and protect this in `[WebThermalMitigationObserver thermalStateDidChange]`
before calling notifyThermalMitigationChanged() on it.
