`HasAbslStringify
<T
>` detects if type `T` supports the `AbslStringify()`
customization point (see
https://abseil.io/docs/cpp/guides/format#abslstringify for the
documentation).
Note that there are types that can be `StrCat`-ed that do not use the
`AbslStringify` customization point (for example, `int`).
