Subject: [PATCH] ExecutorConfigType should be cacheable (#26498)

Apparently the cache_ok attribute must be applied to all subclasses too.  So we must apply it here.  This allows sqlalchemy to use the caching behavior introduced with version 1.4.  See https://docs.sqlalchemy.org/en/14/core/type_api.html#sqlalchemy.types.ExternalType.cache_ok for more info.

(cherry picked from commit ba9edda254a52af6915bd20d569a9f8c8dfb4bf9)
