gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3
This makes it possible to identify gl_TexCoord and gl_PointCoord for drivers where sprite coordinate replacement is restricted. The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum
