mesa: Add SYSTEM_VALUE_VERTEX_ID_ZERO_BASE
There exists hardware, such as i965, that does not implement the OpenGL
semantic for gl_VertexID. Instead, that hardware does not include the
value of basevertex in the gl_VertexID value.
SYSTEM_VALUE_VERTEX_ID_ZERO_BASE is the system value that represents
this semantic.
