wined3d: invalidate streamsrc, vdecl and indexbuffer after strided draws

Please give this patch a try, it fixes at least the disappearing objects issues
for me.

Sacred is one of the few apps that uses the abomination that is
IDirect3DDevice7::DrawPrimitiveStrided. This function bypasses the vertex
declaration. We properly invalidate the vdecl before the draw, but not
afterwards. Prior to the patch that caused the regression, the changed stream
source in the next regular draw would invalidate the vdecl state and everything
was OK. But since this patch we were only rebinding the stream source and not
doing more fundamental things associated with the vertex declaration, like
switching between regular and pretransformed vertices.

Even the past behavior was just luck. We have to invalidate those states before
and after the user-data strided draw. I wish Microsoft had never invented this
method.

The additionally added STATE_STREAMSRC invalidation is technically redundant,
because reapplying STATE_VDECL will reapply STATE_STREAMSRC, but
wined3d_device_draw_primitive_strided isn't supposed to know about this.
