Cache --whitelisted-extension-id in SimpleFeature.
During startup, CommandLine::HasSwitch(kWhitelistedExtensionID) is
called ~1000 times by SimpleFeature. It is the most common switch
lookup, the second being kAppsGalleryUpdateUrl at ~300 times.
Caching this avoids allocating and copying the string each time.
