We have found `_PyErr_Display` to be quite helpful in embedding situations, in particular as a way to capture errors to a custom buffer rather than to `stderr`. Otherwise, embedders often have to replicate logic in `PyErr_Print`, etc. 

Since the header restructuring in Python 3.8+, that function is a bit harder to call. It's exported, but is considered "internal" and thus requires defining `Py_BUILD_CORE`.

I was wondering: why not expose it under "Include/cpython"? It seems like a generic-enough helper, similar to `_PyErr_WriteUnraisableMsg`.
