wined3d: Use dst_fbo to do the depth blit.

This makes the depth copy independent of the currently attached render targets. This is important for the next patch because it might do a depth copy when the render targets aren't in a valid configuration (SetDepthStencilSurface()).

wined3d: Use dst_fbo to do the depth blit.
