  -----------
  [X86] Adjust vector test costs to match SoG (Issue #54889)

znver1/2 models were incorrectly modelling the latency/throughput/uops and znver1 ymm variants also require double pumping.

Now matches what I can decipher from the AMD SoG, Agner and instlatx64 numbers vs the llvm-exegesis report provided by @fabian-r
