Abhishek-Balaji 852576db97 settings: Add preview while uploading custom emoji. ...

This adds a preview of the uploaded emoji image while uploading custom
emoji right below the upload form.

Modified upload_widget.build_widget() to take in the preview
span text and image. In case a parameter isn't passed
for preview text, it defaults to null and the snippets in
build_widgets() related to preview don't run.

Fixes #9229.

Styling tweaked by tabbott.
