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.
