Only provide the resolved activity info to the global intercept window

- Previously we were adding the activity info to the ClipData, but
  that data is provided to non-intercept windows when the drop happens
  and can be retrieved using reflection. The intention was only to
  provide this activity info to the shell global intercept window
  for invoking split.

  Instead of baking the info into the ClipData, we pass the resolved
  info along side the data and only construct a ClipData with the
  additional info for the intercept window.
