Adds a timezonechange event and ontimezonechange event handler to Window and WorkerGlobalScope.


The current timezone is visible to JavaScript and changes over time. Changes may be useful to note, for example, in a long-running calendar or mail application that may want to update dates and times without refreshing when the user resumes using the application after travel. Currently, to accomplish that, a webapp has to poll, for example, by repeatedly call Intl.DateTimeFormat().resolvedOptions().timeZone.
