gallium: remove point_size_min and point_size_max from rasterizer state
The state tracker is responsible for clamping to any graphics API enforced size min/max limits for both the static point_size setting as well as per vertex point size (in the vertex shader). Note that mesa state tracker didn't actually use these values.
