Add private flag PRIVATE_FLAG_HAS_DOMAIN_URLS to ApplicationInfo

This is for supporting Settings UX and Domain URLs

- the new PRIVATE_FLAG_HAS_DOMAIN_URLS flag will be set by
generateApplicationInfo() when the Activity is said to have some
IntentFilter with a VIEW action and a http / https data URI

- code cleaning for args passing
- also add a new constant for the MetricsLogger
