Support launching apps by package name without visibility

PackageManager#getLaunchIntentForPackage returns null if the caller
is not allowed to query the package. This cl adds a new api using
the same implementation with the #getLaunchIntentForPackage. Instead
of returning the Intent, it returns the IntentSender which is not
restricted by package visibility.
