  [CostModel][X86] Update throughput costs for CTLZ ops

This was achieved with an updated version of the 'cost-tables vs llvm-mca' script D103695 (and recent fixes to the bdver2 + alderlake models)

Adding full CostKinds costs are affecting some other tests as they make assumptions about SizeLatency costs, so they need addressing first
