  -----------
  [TTI] Use MemIntrinsicCostAttributes for getGatherScatterOpCost (#168650)

- Following #168029. This is a step toward a unified interface for
masked/gather-scatter/strided/expand-compress cost modeling.
- Replace the ad-hoc parameter list with a single attributes object.

API change:
```
- InstructionCost getGatherScatterOpCost(Opcode, DataTy, Ptr, VariableMask,
-                                        Alignment, CostKind, Inst);

+ InstructionCost getGatherScatterOpCost(MemIntrinsicCostAttributes,
+                                       CostKind);
```

Notes:
- NFCI intended: callers populate MemIntrinsicCostAttributes with same
information as before.
