  [CostModel][X86] Add CostKinds handling for fadd/fsub/fneg ops

This was achieved with an updated version of the 'cost-tables vs llvm-mca' script D103695 which I'll update shortly

As we're using 'typical' worst case values, not all cost entries come from a single CPU - e.g. the latency/throughput from haswell but the size-latency(uops) from zen1/alderlake-e due to 'double pumping'
