bpo-42064: Move sqlite3 types to global state (GH-26537)

* Move connection type to global state
* Move cursor type to global state
* Move prepare protocol type to global state
* Move row type to global state
* Move statement type to global state
* ADD_TYPE takes a pointer
* pysqlite_get_state is now static inline
