vo_gpu: libplacebo: simplify tex transfers for libplacebo 168+
Upstream libplacebo got refactored to use byte-sized strides rather than texel-sized strides. This commit makes mpv's ra_pl wrapper take advantage of that, rather than forcing a stride-fixing memcpy. Note that, technically, we would still need a stride fixing memcpy in cases when the true stride is not a multiple of the format's texel *alignment*, however this is a much rarer case and extremely unlikely to occur in practice, since all relevant formats use power-of-two texel alignments.
