[CodeGen] Update for scalable MemoryType in MMO (#70452)
Remove getSizeOrUnknown call when MachineMemOperand is created. For Scalable
TypeSize, the MemoryType created becomes a scalable_vector.
2 MMOs that have scalable memory access can then use the updated BasicAA that
understands scalable LocationSize.
