提示词：补齐 PythonPlugin C API WASM shim 符号

Browse Source 
结论：按 LinuxCNC src/emc/pythonplugin/python_plugin.cc 的初始化、导入、配置和 callable 调用路径，把 PyConfig/PyStatus、PyImport_*、PyDict_SetItemString、Py_InitializeFromConfig、PyRun_SimpleString、Py_GetVersion、PyObject_Call 等符号纳入 inert WASM Python C API shim；真实 Python 执行仍保持禁用。

检查：./test-linuxcnc-wasm-python-c-api-symbols.sh 通过；./test-native.sh 通过；./test-linuxcnc-source-link.sh 通过。
