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.
