[dynamo][hf_bigbird] Actually graph break on tensor.unsqueeze_/resize_ (#99986)
Currently, we return `unimplemented` w/o a graph break on seeing a x.unsqueeze_ when x is input. This essentially means we fall back to the original frame.
This PR actually graph breaks so that we can generate the continuation frame for the rest of the function. Instead of graph breaking at LOAD_ATTR, we delay the graph break to the actual CALL_FUNCTION, where its cleaner to graph break.
