[issue28748] Make _Py_PackageContext of type "const char *"

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Currently _Py_PackageContext has type "char *". But it is either NULL or a pointer to internal readonly UTF-8 representation of Unicode object. Adding the const qualifier makes it clear that the data is immutable. I don't think this change will break third-party code.
