This experiment replaces the label used in the aaxfermodes gm with aliased text generated from paths common to all platforms. Since there is no way today to generate all dm output from trybots, this will be checked in to confirm that this strategy provides simpler output across devices. This does not introduce a new public interface; instead, dm uses a extern backdoor to install the SkTypeface::CreateFromName handler. Review URL: https://codereview.chromium.org/1163283002
