svga: return 1 for PIPE_CAP_VERTEX_COLOR_UNCLAMPED query

Browse source 
Before, we weren't clamping the vertex colors produced by ARB vertex
programs.  This could result in some rendering being too bright (in
ETQW, for example).

Also add cases for PIPE_CAP_VERTEX_COLOR_CLAMPED and
PIPE_CAP_FRAGMENT_COLOR_CLAMPED with comments to be complete.
