This unifies the plug-in information dictionaries vended by WKContextCopyPlugInInfoForBundleIdentifier
and WKContextGetInfoForInstalledPlugIns with those from the WKPageLoaderClient and WKPageUIClient.

All the old keys will continue to work, but have been deprecated in favor of new keys defined in 
WKPluginInformation.h
