gallium: rework handling of sprite_coord_enable state
Implement the pipe_rasterizer_state::sprite_coord_enable field in the draw module (and softpipe) according to what's specified in the documentation. The draw module can now add any number of extra vertex attributes to a post-transformed vertex and generate texcoords for those attributes per sprite_coord_enable. Auto-generated texcoords for sprites only worked for one texcoord unit before. The frag shader gl_PointCoord input is now implemented like any other generic/texcoord attribute. The draw module now needs to be informed about fragment shaders since we need to look at the fragment shader's inputs to know which ones need auto-generated texcoords. Only softpipe has been updated so far.
