svga: support TGSI_SEMANTIC_TEXCOORD in swtnl draw context

Browse source 
Since PIPE_CAP_TGSI_TEXCOORD is now enabled, texcoord is now declared
as TGSI_SEMANTIC_TEXCOORD instead of TGSI_SEMANTIC_GENERIC.

Fixes assert running REDTurbineDEMO with MTL Renderer when the guest needs to
fallback to swtnl for line stipple.

Fixes: e73443b7a5 ("svga: enable PIPE_CAP_TGSI_TEXCOORD for vgpu10 and up")
