Auto merge of #15174 - DexterHaslem:15165-webkit-text-stroke-sh-ord, r=SimonSapin

make -webkit-text-stroke color and width shorthand no longer sensitive to ordering

<!-- Please describe your changes on the following line: -->
this makes `-webkit-text-stroke` shorthand work with line-width and color in either order.

I added a shorthand parser test to the existing inherited_text test, which wasn't very similar to any of the other tests in there, hope sticking shorthand below the longhand stuff is ok.
