[ODS] Fix operation argument population to avoid crash
The `Operator` class keeps an `arguments` field, which contains pointers to `operands` and `attributes` elements. Thus it must be populated after `operands` and `attributes` are finalized so to have stable pointers. SmallVector may re-allocate when still having new elements added, which will invalidate pointers.
