[chromium] revert getFontDataForCharacters change
Created attachment 54629 [details] Patch
We hit this code path repeatedly while rendering. It wasn't so bad before (since it was just computing a font name) but it is very bad now (since we're loading a font).
LGTM. (I think a rollout is permitted without a real WebKit review so you could just land this now.)
