    radv: don't emit unneeded vertex state.

    If the number of instances hasn't changed and we've already
    emitted it, don't emit it again.

    If the vertex shader is the same and the first_instance, vertex_offset
    haven't changed don't emit them again.

    This increases the fps in GL_vs_VK -t 1 -m -api vk from around 40
    to around 60 here, it may not impact anything else.

    Dieter also reported smoketest going from 1060->1200 fps.
