Add a print icon

[Josh68]

What

MCT has been using FontAwesome for several icons, and now we're stripping it out in favor of CMSDS icons. The only thing we're missing right now is a print icon, like this. I am hacking it in using SVGIcon and a path copied over.

Why

• Allows us to abandon 3rd-party icons, which have accounted for a sizeable amount of extra payload
• It does not exist in the DS as its own icon
• We use this icon all over MCT, and it appears HC.gov could also use one

Hi! I'd like to help with this. If one of the maintainers (@pwolfert? @Karak888?) approves, I'll take on creating one to add to the the supplemental set.
