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. (cherry picked from commit 063db62) Co-authored-by: xdegaye <xdegaye@gmail.com>

By default, modules configured in `Modules/Setup` are no longer built with
