We should allow the embedder to customize the suspension delay for WebContent. I've been using this
to set a much shorter delay to help flush out issues with spurious wakeups of suspended processes.

Originally I tried doing this via UnifiedWebPreferences, but that doesn't really buy us a whole lot
since a preference with a float or int type doesn't seem to participate in a lot of the useful
auto-generated _WKInternalDebugFeature lists that the browser consumes. So I just put the value in
PageConfiguration instead.
