Convert macros to static inline functions to avoid macro pitfalls, like duplication of side effects:

  • _PyObject_SIZE()
  • _PyObject_VAR_SIZE()

The result type is size_t (unsigned).

I prefer to mark this PR as a draft for now, until a decision is taken on issue #99845 about signed vs unsigned types, and wait until preparation PRs (fix usage of these macros) are merged first.
