    gpu: add dummy pl_gpu backend · 5d0c1f8d

    This is basically a software emulated `pl_gpu`, which does all
    texture/buffer operations in host memory using CPU instructions.
    
    Attempting to somehow soft-emulate shaders or rasterize is _way_ out of
    scope for this dumb thing, so we don't support `pl_tex_blit` or
    `pl_pass` at all. Literally the only point is to let users generate
    "faux" shaders, while keeping track of the generated LUTs etc.
