Previously, if a classifier was set and build-image was executed from
the command-line, the build will fail as the plugin was unable to find
the original jar. This is because it relies on the attached artifacts
of the project, and those are not set when package has run as part of
a forked lifecycle.
This commit makes sure that the backup file is found by convention
first, the same way it is done for the target file.

An `imagePlatform` option for the Maven and Gradle image-building
goal/task can be used to specify the os/architecture of any
builder, run, and buildpack images that are pulled during image
building.
Closes gh-40944
A `trustBuilder` configuration option has been added to the Maven and
Gradle CNB integration image building goal and task. A known set of
builders published by Paketo, Heroku, and Google are trusted by default,
all other builders are untrusted by default.
