gh-128013: Convert unicodeobject.c macros to functions (#128061)
Convert unicodeobject.c macros to static inline functions. * Add _PyUnicode_SET_UTF8() and _PyUnicode_SET_UTF8_LENGTH() macros. * Add PyUnicode_HASH() and PyUnicode_SET_HASH() macros. * Remove unused _PyUnicode_KIND() and _PyUnicode_GET_LENGTH() macros.
