  [CostModel][X86] Adjust fp<->int vXi32 SSE legalized costs based on llvm-mca reports.

Building on rG2a1ef8784ad9a, adjust the SSE cost tables to use the legalized types based on the worst case costs from the script in D103695.

To account for different numbers of src/dst legalized type registers we must scale the cost by maximum of the src/dst, not just use src
