[CostModel][X86] Adjust fptosi/fptoui SSE/AVX legalized costs based on llvm-mca reports.

Update (mainly) vXf32/vXf64 -> vXi8/vXi16 fptosi/fptoui costs based on the worst case costs from the script in D103695.

Move to using legalized types wherever possible, which allows us to prune the cost tables.
