Update ChooserTarget constructor to take ComponentName, Bundle

Simplify ChooserTarget handling by requiring a target component and an
extras bundle instead of a full PendingIntent/IntentSender. This
simplifies the handling of URI grants from sending apps.

Prune ChooserTargets that point at ComponentNames that don't share a
package with the original matching Activity target or that aren't
exported so that we don't show the user something they can't launch.
