Clean up NotificationRowBinderImpl

Clean up a few things in NotificationRowBinderImpl

*Remove a bunch of dead parameters and methodsd
*Split logic into three main helper methods
   1) bindRow - called once when row is made
   2) updateRow - called to update row view state whenever the
   notification is updated
   3) inflateContentViews - called to initiate row content inflation
   whenever notification is updated
*Try to move other logic to appropriate places
  -Mainly move targetSdk resolution to be right after setting the sbn
  instead of after the row is inflated. This also makes icons neater to
  manage since we can immediately set the tag
