> #89178 is related I think. If we want to go ahead with that, maybe we want to rename this to `_LIBCPP_HAS_EXPERIMENTAL_TZDB` or `_LIBCPP_HAS_EXPERIMENTAL_FEATURE_TZDB`. FWIW just `_EXPERIMENTAL_` makes it sound to me like it's in `std::experimental`.

The new name matches existing names. So I prefer to have one pattern. This name was recently discussed on Discord too.
