This commit adds a --verbose flag to the run-org-model.py script to
enable or disable detailed debug output, such as input and output
tensors for each layer. Debug utilities (summarize, debug_hook,
setup_rope_debug) have been moved to utils/common.py.
The motivation for this is that the detailed debug output can be useful
for diagnosing issues with model conversion or execution, but it can
also produce a large amount of output that may not always be needed.
The script will also be further cleaned/refactored in follow-up commits.
