Lock `ZoneInfoType` to protect accesses to `ZONEINFO_STRONG_CACHE`. Refactor the `tp_new` handler to use Argument Clinic so that we can just use `@critical_section` annotations on the relevant functions. Also use `PyDict_SetDefaultRef` instead of `PyDict_SetDefault` when inserting into the `TIMEDELTA_CACHE`.
