[Feature Request] Deep Learning AMI EC2 Image Builder Component

AWS vends [Deep Learning AMIs](https://aws.amazon.com/machine-learning/amis/) to help customers get started with ML training quickly. However, customers already have existing Image Builder pipelines building off a specific Amazon Linux version or AMI and would prefer not to introduce an additional AMI type to support.

This feature request is for Image Builder to introduce a new Deep Learning AMI component such that customers can use their existing AMI choice and add an option to add configurations to the AMI via the component to have the AMI operate like the Deep Learning image of choice.

The issue names no repository files, tests, or entry points. Start by reviewing the EC2 Image Builder component model and the referenced Deep Learning AMI requirements. Done means the scope and behavior of a component that adds the requested Deep Learning AMI configuration to an existing AMI choice are defined.
