radv/meta: move clear color to using push constants
The color clear value is uniform and needs only to be emitted from the frag shader, so just push it down via a push constant, and remove the vertex buffer completely. The depth clear value needs to be emitted from the vertex shader, but is only a single value. Reviewed-by: Bas Nieuwenhuizen <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
