[Settings] Additional route for dismiss activity dialog

Previous design dismiss an activity dialog through Intent would lead to a pair of creating and finishing activity. The task switch during the creating and finishing may introduce some side effect to the other apps.

This change tried to add additional route to avoid from dismiss through Intent
but sending an async close request to that specific dialog (if available).
