// Determines if the quiet prompt UI should be used to display a notification
// permission request on a given site. This is the case when:
//  1) the quiet UI is enabled in prefs for all sites, either directly by the
//     user in settings, or by the AdaptiveQuietNotificationPermissionUiEnabler.
//  2) the quiet UI is triggered by crowd deny, either through:
//     a) CrowdDenyPreloadData, that is, the component updater, or
//     b) CrowdDenySafeBrowsingRequest, that is, on-demand Safe Browsing pings.
// If both (1) and (2) are fulfilled, the crowd-deny UI is shown.
//
// Each instance of this class is long-lived and can support multiple requests,
// but only one at a time.
