Contributor

We have clusters doing non-volatility sanity checks, but for external
attributes we can't conclusively say they are volatile, and the
clusters don't work right if we assume they are. So instead assume
that if the spec says N the external attribute is in fact
non-volatile.

Fixes #20093

Problem

Can't correctly implement some clusters on a dynamic endpoint (so using external attr storage).

Change overview

Loosen the checks to treat external attributes as presumptively non-volatile as needed.

Testing

Should pass existing CI.
