#14640 Simulator Events: Use one experimental feature flag

The import and schedule export of simulator events are two halves of the same
workflow, so they share the "simulator-events" flag instead of having one
keyword each. Users who enabled "simulator-events-import" have to tick the new
entry once in Preferences -> System -> Experimental Features.
