Add IntentFilter auto verification - part 4

- add domain verification priming at boot when the PackageManagerService
singleton is created. This will mainly set the domain verification status
to INTENT_FILTER_DOMAIN_VERIFICATION_STATUS_ALWAYS for all Apps that
have an IntentFilter with action VIEW and data scheme HTTP or HTTPS.

- also optimize Intent resolution by taking into account Browser Apps
