External link icon for larger font sizes

[annapowellsmith]

Please could we have an additional external link icon to use with larger font sizes?

We have a design that has a rel="external" link in 24px and it would be great to use the external link icon with it. The current image isn't big enough to look good.

https://github.com/alphagov/govuk_frontend_toolkit/blob/master/stylesheets/_typography.scss#L334-400 is the relevant code.

[From the frontend meeting] For any new external link styles, please raise a PR on the front end toolkit, we're happy to merge if the need is made clear.

We have ended up using an SVG icon for the external link icon due to the numerous cases of sizes/colors we require it in. Moving forward I can't see any other option than to provide SVG.

Getting #293 would also solve this issue as that would remove all external link icons.

External link icons were removed in #293, so this can be closed.
