CultMath: regenerate snoise golden values for the upstream kernel

Browse source 
Seven values change: four snoise(float3) in HlslSemanticsTests and three snoise(float2)
in MathTests (the 2D (0,0) golden is 0 either way). Regenerated from the code after the
continuity probe passed. The tests no longer claim to match Unity.Mathematics, whose
snoise keeps the old constants.
