Add a new `build-image` goal to the Maven plugin to allow Docker images
to be create via using the cloud native buildpack.

See gh-19830

Pull functionality from `Repackager` into a new `Packager` base class
and develop a variant for Docker image creation. The new `ImagePackager`
class provides a general purpose way to construct jar entries without
being tied to an actual file. This will allow us to link it to a
buildpack and provide application content directly.

Closes gh-19834

Add a Java implementation of the buildpacks.io specification allowing
projects to be packaged into OCI containers. The `builder` class
provides a Java equivalent of `pack build` command and is based on
the `pack` CLI Go code published at https://github.com/buildpacks/pack.
