* @brief Common InferShape method, supporting full-graph inference and targeted op inference.
*
* @param function The function on which shape inference is to be performed.
* @param targetOps List of target operations to infer shapes for. If empty, inference is performed
* on all operations in the function. If non-empty, only the specified operations
* are inferred, but it is required that targetOps includes all necessary
* dependent operations; otherwise, topological ordering and inference may be incorrect.
* @return Status Operation result, SUCCESS indicates success, FAILED indicates failure.
*
* @note When targetOps is non-empty, only the operations in targetOps are included in the operation set,
* and only edges between operations within targetOps are added during dependency graph construction.
* The caller must ensure that targetOps contains all required dependent operations, or that the
* DynValidShape of those operations is already correctly set, to avoid inference errors caused by
* dependency truncation.
