Update enforce intent filter match implementation

1. Guard the feature with proper feature flagging
2. Gate the behavior with target SDK >= V
3. Ignore default only flags when enforcing the intent filter matching,
   or else some activities will not be accessible by any intent (e.g.
   launch activities use the catagory LAUNCHER instead of DEFAULT, which
   means intents returned from PackageManager#getLaunchIntentForPackage
   cannot be started by any means).
