bpo-32232: by default, Setup modules are no longer built with -DPy_BUILD_CORE (GH-6489) 

Setup modules are no longer built with -DPy_BUILD_CORE by default,
as using that flag may now require including additional internal-only header files.

Instead, only the modules that specifically need it use that setting.

By default, modules configured in `Modules/Setup` are no longer built with
`-DPy_BUILD_CORE`. Instead, modules that specifically need that preprocessor
definition include it in their individual entries.
