Make a deep copy of the _default_attributes in column_defaults
When column_defaults is called it calls `value` on each instance of
Attribute inside the _default_attributes set. Since value is memoized in
the Attribute instance and that Attribute instance is shared across all
instances of a model the next call to the default value will be memozied
not running the proc defined by the user.
Fixes #33031.
