Reviewed by Antti Koivisto.

The baseline-shift CSS property is represented by two different bits on RenderStyle. In the case of
"inherit" we would only forward one of the bits from the parent style. We now add a custom "inherit"
function to the style builder to correctly forward both bits from the parent style.

This fixes the remaining tests in the web-animations/responsive/baselineShift.html WPT which uses
"baseline-shift: inherit" in a @keyframes rule.
