  [Attributor] Only manifest pointer operand for `StoreInst` in `AAAddressSpace` (#65708)

`AAAddressSpace` currently only works for `LoadInst` and `StoreInst`
currently. For `StoreInst`, the corresponding use can be the pointer
operand, or value operand, or both. When it is used as value operand, it
can prevent `AMDGPUPromoteAlloca` from optimization in certain cases.
This patch changes the manifest method such that only pointer operand
will be rewritten.
