Extend FKUserDefaultsPlugin to support app suite user defaults.

Browse Source 
Summary:
`FKUserDefaultsPlugin` is initialized with an `appSuiteName` but doesn't use this to monitor the app suite user defaults. This adds that capability.

In Flipper, "App Suite UserDefaults" defaults will show up in the drop down selector for user defaults.
