Let the user set an alt on the image

[IchordeDionysos]

iron-icon has no way for us developers to help disadvantaged users who use a screen reader to understand what the meaning of the icon in this situation is.

Expected outcome

We as developers define an alt-attribute on the element and a screen reader announces the text provided in the ways ARIA best practices define.

Actual outcome

There is no way official way to announce a text.

Live Demo

<iron-icon icon="icons:accessibility" alt="Example for icon accessibility"></iron-icon>

Could the attribute "title" be a workaround for this?
