Update base for Update on "[ET-VK][ez] Constrain out repsets individually"

Address the TODO comment in the `tag_memory_meta_pass.py` graph pass.

```
        # TODO(ssjia): For most ops, inputs and outputs must be synchronized, so there
        # is no need to constrain output repsets explicitly. Currently, the exceptions
        # (i.e. choose qparams) already define constrined repsets for the output, so
        # there is again no need to explicitly constrain the outputs. If an operator
        # appears later on that does not sync input and output representations, and
        # defines ambiguous repsets for the output tensor(s), then we will need to add
        # additional logic to this function to constrain the output repsets separately
        # from the input repsets.
```

This condition is now fulfilled with the below diff.
