Bug 1993608 [wpt PR 55327] - Blink: Fix unit conversion for relative oklch() angle components., a=testonly

Automatic update from web-platform-tests
Blink: Fix unit conversion for relative oklch() angle components.

This fix ensured the correct interpretation and conversion of the units
of colors in oklch().

The bug looked at a sample of these two identical colors background:
oklch(from blue .5 .3 180deg); background: oklch(from blue .5 .3
.5turn); While both of these colors should have been green (as on other
browsers). However, in Chrome, the top sample was green as expected
while the bottom sample was red.

This issue was traced to a missing conversion to degrees with
ComputeDegrees() in UnresolvedRelativeColor.
