I broke it with PR #265. I was testing with a model where the wk_b and wk_v tensors were present, so didn't need to be computed, so didn't notice that the change I made to ggml_compute_forward_dup_q breaks that computation.

Somehow I had the concept that
Q8_0KV cache is working for CPU-only inference with FlashMLA-2. Indeed it is for prompt processing, but not for TG (two different paths are taken). Clearly too many options as I'm getting confused myself. Anyhow, this PR adds the missingQ8_0 -> Q8_0contiguous transpose operation, so now we can useQ8_0KV cache with FlashMLA-2 also on the CPU.
