    st/mesa: accelerate glGetTexImage for all formats using a blit

    This commit allows using glGetTexImage during rendering and still
    maintain interactive framerates.

    This improves performance of WarCraft 3 under Wine. The framerate is
improved
    from 25 fps to 39 fps in the main menu, and from 0.5 fps to 32 fps in the
game.

    v2: fix choosing the format for decompression
