Experiment: decouple types.DynamicClassAttribute from property

[tungol]

I'm curious to see what the tests look like.

Less breakage than I imagined. "Run mypy against the stubs" passes for 3.11+, which I suspect means that enum.property being named property is sufficient to get (some of) the special treatment, but the primer results show it's not all of it. One other thing I want to try.

Diff from mypy_primer, showing the effect of this PR on open source code:

Subclassing doesn't appear to make any difference.

It's actually because mypy hardcodes in some extra special casing to cope with typeshed's stubs here. See python/mypy#14133

Thanks for the context, I appreciate it
