Constexpr `entt::any`

[n0F4x]

I have a lot of constexpr code that can also be tested at compile. I was hoping that entt::any would be constexpr, but it wasn't.
This isn't really a high priority issue. Maybe someone else will also find it useful sometime in the future. Who knows...

entt::any is not designed to be constexpr, I'm sorry. So, this is a sort of invalid issue.
However, what would be the benefit? I'm curious now. I don't see many uses of a constexpr version.

I only use it for testing at this point. But later I could use to e.g. construct everything I can at compile time when the program starts.
I also just rolled my own constexpr any (link).

A lot of standard containers are becoming constexpr (link). It would be so cool if EnTT could have its constexpr any before the standard.
