Part of #626 Fixes #15911 Introduces a new `IMaterializationInterceptor` singleton interceptor that allows: - Interception before any entity instance has been created, allowing a customized instance to be created (if desired), thereby suppressing of normal EF instance creation. - Interception after the instance has been created, but before property values have been set. The instance can be replaced with a new instance (if desired), without preventing EF from setting property values. - Interception before property values have been set, allowing custom setting of the values and/or suppression of setting the values by EF (if desired). - Interception after property values have been set, allowing the instance to be changed (if desired.) Access to property values, including shadow and service properties is provided at each point. If no singleton materialization interceptors are configured, then the materialization delegate is the same as before, meaning any perf impact only applies if interception is used.
