Auto merge of #11273 - mbrubeck:fast-shape, r=pcwalton

Add a fast path for shaping ASCII text

On both my Linux laptop and iMac, this is about twice as fast as Harfbuzz text shaping on https://en.wikipedia.org/wiki/Barack_Obama.

I haven't tested this on any high-DPI (retina) displays, and I'm not 100% certain that the font unit scaling is correct there.

Depends on servo/core-text-rs#50.
