Make icons accessible.

### Describe the feature you'd like
The ability to select icons through accessible means. For example in a current codebase we have a duplicate of the download icon like this:

```
const DownloadIcon = ({
color = Colors.ACTION_BLUE_900,
className,
title = 'download icon',
titleId,
}: {
color?: string
className?: string
title?: string
titleId: string
}) => {
return (

)
}
```
This allows you to specify a title for the icon and then reference it accessibly, it might be nice if instead of passing an id for the title it could be autogenerated.

### Describe alternatives you've considered
Wrapping the parent components in the accessible attributes, this might work for buttons but there might be other states where icons are displayed only as informative.
