Deprecating some usages of download snackbar in favor of infobar

This CL removes some usages of download snack bar since essentially download
infobar has replaced it for showing download progress. However there are
certain failure messages that are not covered which are not exactly related
to an active download. For those messages, snack bar will continue to show.
