This commit adds a check to the support code for the Gradle plugin
bootBuildImage task to ensure that the jar file that will be passed
to a builder is readable and has a valid directory. This prevents a
situation where the jar file cannot be read because it is prepended
with a launch script, and the builder does not receive any files to
process.
Notes have also been added to the Gradle plugin documentation to warn
against using a bootJar launchScript configuration and bootBuildImage
together, as well as caveats about launchScript that match the Maven
plugin documentation.

This commit improves the validation performed on the user
input provided to the layertools jarmode to provide more
clear error messages when the input is not correct and
reduce the chance of ambiguity.
Fixes gh-22042
Rename `ImageReferenceParser` to `Regex` and remove state. The regular
expressions are now used directly by the `ImageName` and
`ImageReference` classes with the values accessed directly from the
`Matcher`.

Prior to this commit, an image name or run image name derived from
the project name or provided by the user would be passed to the CNB
builder without validation by the Maven plugin build-image goal or
Gradle plugin bootBuildImage task. This could lead to error messages
from the plugins that are difficult to understand and diagnose.
This commit makes parsing of the image names more strict, based on
the grammar implemented by the Docker go library. This provides
validation of the image names before passing them to the builder,
with a more descriptive error message when parsing and validation
fails.
