Title: fix #2562 -- Apply new volume-overlay visual and some vibration logic changed

fix #2562,
this PR changes the setting of vibration when pressing hardware volume keys, using mozSettings `phone.vibration.incoming`,
but `sms.vibration.recieved` is not manipulated. Could be modified later when UX confirmed.
(Do we really need sms vibration settings? Neither iOS or Android has separated the vibration setting into 2 different cases.)
