bpo-45573: Introduce extension module flags in Makefile (GH-29594)
``configure`` now uses a standardized format to forward state, compiler flags, and linker flags to ``Makefile``, ``setup.py``, and ``Modules/Setup``. ``makesetup`` use the new variables by default if a module line does not contain any compiler or linker flags. ``setup.py`` has a new function ``addext()``. For a module ``egg``, configure adds: * ``MODULE_EGG`` with value yes, missing, disabled, or n/a * ``MODULE_EGG_CFLAGS`` * ``MODULE_EGG_LDFLAGS`` ``Makefile.pre.in`` may also provide ``MODULE_EGG_DEPS`` that lists dependencies such as header files and static libs.
