Summary Hue interpolation "specified" is not correctly implemented for hues < 0 or > 360

We currently normalize hues (for CSS color functions hsl(), hwb(), lch(), and oklch()) to aggressively, and should instead be deferring normalization (hue % 360) until necessary, either because a conversation or interpolation method requires it. This should allow us to implement the "specified" hue interpolation method, which allows for the hue to circle the spectrum multiple times if necessary (i.e. 0 -> 720 would be two revolutions).
