Integrate magi_compiler as a new backend for graph_net_bench: - Static path (no sympy dynamic dims): TORCH_COMPILE + inductor via magi_compiler._api._magi_compile_class, bypassing the public API assert that requires non-empty dynamic_arg_dims - Dynamic path (sympy symbols in input_tensor_constraints.py): MAGI_COMPILE piecewise via magi_compiler.magi_compile _load_dynamic_arg_dims reads input_tensor_constraints.py from the model's source directory and extracts only the truly dynamic dims (args whose shape contains sympy.Basic symbols), avoiding ConstraintViolationError caused by magi_compiler's default heuristic marking all tensors as dim-0 dynamic.

Summary
MagiCompilerBackend，将magi_compiler接入graph_net_bench编译器测试框架input_tensor_constraints.py中无 sympy 动态维度）：走TORCH_COMPILE + inductor，通过magi_compiler._api._magi_compile_class绕过公开 API 对非空dynamic_arg_dims的 assertMAGI_COMPILE piecewise，通过magi_compiler.magi_compile正常编译_load_dynamic_arg_dims读取模型目录下的input_tensor_constraints.py，仅提取含sympy.Basic的真实动态维度，避免 magi_compiler 默认启发式将所有 Tensor 标为 dim-0 动态导致的ConstraintViolationErrortest_compiler.py中注册magi_compiler编译器名Test plan
