Fix shift/mask error in ArtbEvaluator
Shifting from the left copies the MSB along with it. This causes a problem
in ArgbEvaluator, which shifts the top byte down by 24 for the start/end
colors, and then uses those values to interpolate alpha values. The correct
appraoch (used with the other color components) is to mask by 0xff after the
shift.
Issue #6960514 External bug: ArgbEvaluator can't evaluate alpha value properly
