gh-111506: Add _Py_OPAQUE_PYOBJECT to hide PyObject layout & related API (GH-136505) 
Allow Py_LIMITED_API for (Py_GIL_DISABLED && _Py_OPAQUE_PYOBJECT)


API that's removed when _Py_OPAQUE_PYOBJECT is defined:

    - PyObject_HEAD
    - _PyObject_EXTRA_INIT
    - PyObject_HEAD_INIT
    - PyObject_VAR_HEAD
    - struct _object (i.e. PyObject) (opaque)
    - struct PyVarObject (opaque)
    - Py_SIZE
    - Py_SET_TYPE
    - Py_SET_SIZE
    - PyModuleDef_Base (opaque)
    - PyModuleDef_HEAD_INIT
    - PyModuleDef (opaque)
    - _Py_IsImmortal
    - _Py_IsStaticImmortal

Note that the `_Py_IsImmortal` removal (and a few other issues)
 means _Py_OPAQUE_PYOBJECT only works with limited
API 3.14+ now.

gh-129666: Add C11/C++11 to docs and -pedantic-errors to GCC/clang test_c[pp]ext tests (GH-130692) 
Disable pedantic check for c++03 (unlimited API)

Also add a check for c++03 *limited* API, which passes in pedantic mode
after removing a comma in the `PySendResult` declaration, and allowing
`long long`.

gh-92906: Enable test_cext and test_cppext on Windows (#117000) 
On Windows in release mode, the test_cext and test_cppext can now
build C and C++ extensions.

* test_cext now also builds the C extension without options.
* test_cppext now also builds the C++ extension without options.
* Add C++14 test to test_cppext; C++11 is not supported by MSVC.
* Make setup_venv_with_pip_setuptools_wheel() quiet when
  support.verbose is false. Only show stdout and stderr on failure.
