Compare variation settings assignment on Blink side in: FontPlatformData FontCustomPlatformData::fontPlatformData

and
void SkTypeface_FreeType::Scanner::computeAxisValues
which iterates over font properties and picks the first one.

Spec ref:
https://drafts.csswg.org/css-fonts-4/#propdef-font-variation-settings
"If the same axis name appears twice, the second one supercedes the first."

Also, ~line 2265 in SkFontHost_Mac.cpp 
            double value = defDouble;
            for (int j = 0; j < paramAxisCount; ++j) {
                if (paramAxes[j].fTag == tagLong) {
                    value = SkTPin(SkScalarToDouble(paramAxes[j].fStyleValue),minDouble,maxDouble);
                    break;
                }
            }

commit 9aec8945f0e0cc88c33c2440f2163d36c7198bf6

Use last value for axis for variation position.

SkFontArguments::VariationPosition may be over specified. If there are
multiple values for a given axis, ensure the last value specified is
used, since that's what css-fonts-4 requires.
