Description

• Add a "Shadow normal bias" property to the 3D spot light and the 3D point light, in the "Shadow" group (advanced), with its expression, condition and action.
• It reduces "shadow acne" on surfaces lit at a grazing angle, without moving shadows away from objects like the shadow bias does.
• The value is a number of shadow map texels, measured at the farthest lit distance: the cone length for spot lights and the range for point lights (or the shadow camera far plane when there is no limit).
• It is updated when the cone length, the range, the cone angle, the shadow quality or the shadow camera far plane change.
• The default value is 1, like how we did on the Directional Light on layers

• Let's bump the minor version only
• Let's simplify a tad the description, it's not super user friendly I think
