HHH-13103 added support for getting access to configuration properties when instantiating a Hibernate Type.

However, there are still two issues I'm facing in the [Hibernate Types project](https://github.com/vladmihalcea/hibernate-types):

• the new TypeBootstrapContext only works from 5.4.13 onwards, so if I add this constructor, any prior Hibernate version will fail with a NoClassDeffFoundError.
• I need to get access to the underlying Driver Type to adjust how a certain Type handles arrays, for instance.

For this reason, I propose we inject the SessionFactoryImplementor when initializing the Type if there is a matching constructor taking this argument.
