gh-81057: Generate a Separate Initializer For Each Part of the Global Objects Initializer (gh-99389)
Up until now we had a single generated initializer macro for all the statically declared global objects in _PyRuntimeState, including several one-offs (e.g. the empty tuple). The one-offs don't need to be generated, but were because we had one big initializer. Having separate initializers for set of generated global objects allows us to generate only the ones we need to.  This allows us to add initializers for one-off global objects without having to generate them.
