Invoke a runnable in the extension context. The extension context wraps the method that
gets executed and a full customized configuration (both instance and method specific
configuration customizers have been applied). The extension context is registered with
the underlying handle to configure the handle when calling the {@link Runnable#run()} method.

This method is used by the generated classes from the <code>jdbi3-generator</code> annotation
processor to execute predefined {@link ExtensionHandler} instances.
