st/vega: Add DRAWTEX renderer state.

This state provides glDrawTex-like function.  It can be used for
vgSetPixels.

Rather than modifying every user of the renderer, this commit instead
modifies renderer_copy_surface to use DRAWTEX or COPY state internally
depending on whether the destination is the framebuffer.
