std::any in pybind11/stl.h?

[NAThompson]

A number of C++17 containers, such as std::variant, std::optional, and std::filesystem have "pre-packaged" wrappers in pybind11.

Would it be sensible to add std::any to the list? It feels that it is not much different that std::variant.

Sorry, looks like this is a duplicate of #1590.
