Arm backend: Update parse_test_name script

[AdrianLundell]

• Make TARGETS a list to preserve order.
• Replace edge_ops with a dict mapping test op names to edge op names, e.g. op_name_map["split_tensor"] = "split_copy.Tensor"

Both changes are slightly less efficient compared to using sets, but more convenient to use when handling the results.
