Review comment:
Hmm can you use the functions in `python/tvm/relay/frontend/common.py`
or modify them slightly there to support your need?

Review comment:
Would axis=1 be a more useful default? (since the channel dimension is
usually in dim 1)?

Review comment:
Should this be a cast_like or do we always want things to be int32?

Probably want a comment or check on what the type for weight_zero_point
can be and why
