Also adds WPT reftests to validate alignment behavior in horizontal and vertical writing modes with the different `alignment-baseline` values. Additionally: - The `alignment-baseline: middle` tests have failing expectations. This is because the existing implementation does not match the css-inline-3 definition (which the new WPTs follow). See Bug 2030203. - The WidthTest-Regular.otf support font was updated to remove its unusual ideographic-under baseline value, which affected its synthesized central baseline. With the new support for `alignment-baseline: central`, this broke a number of `text-combine-upright-compression-*` WPT reftests. The non-centered baseline values were removed from this test using FontForge, so that the synthesized central baseline matched the expectation of the test references.
