Bug 1442142 [wpt PR 9731] - [css-typed-om] Fix computed value of an i…

…nterpolated transform., a=testonly Automatic update from web-platform-tests[css-typed-om] Fix computed value of an interpolated transform. Previously we did not handle the case of computing the value of an interpolated transform, which occurs when we interpolate between two different transform types containing percentages. The correct result is currently not spec'd [1], so this patch fixes this by just returning "none" in this case.
