implement content hashing for custom_op, not identity

Fixed critical SQL caching issue where use of the :meth:`_sql.Operators.op`
custom operator function would not produce an appropriate cache key,
leading to reduce the effectiveness of the SQL cache.

Fixes: #9506
Change-Id: I3eab1ddb5e09a811ad717161a59df0884cdf70ed
