SpringBoot Add TaskDecorator support for scheduled tasks

Spring Framework has added TaskDecorator support in https://github.com/spring-projects/spring-framework/issues/23755.

Right now, we auto-configure TaskDecorator for task execution, but not for task scheduling. I think we should also support TaskDecorator beans for task scheduling.
