Add support for creating a container from a TestImage value

This commit improves TestImage so that an explicit image can trigger
the creation of the container, with optional additional setup. This
removes the need of creating additional container types for images that
have multiple flavors, and to please the static method that can only
create a container based on a single match.

Closes gh-51082
