[14/16] WineD3D: Remove the unused stateblock vertex blend member

[Stefan Dösinger]

the vertex_blend member is just a copy of the WINED3DRS_VERTEXBLEND render 
state. It is only written to the stateblock and copied to new stateblocks, 
but never actually read. Remove the redundant value copy and the code setting 
it.

WINED3DRS_VERTEXBLEND isn't supported right now, and the fixed function opengl 
pipeline can't do it, so its mapped to state_nogl. To implement it a pipeline 
replacement shader would be needed.
