Ability to run a Reproducible Build comparison Jenkins job to Verify two MacOS builds are identical

[zdtsw]

To aid verification of reproducible MacOs builds, it would be nice to have a Jenkins job that takes parameters like:

JDK 1 download "URL"
JDK 2 download "URL"
Platform (eg.MacOS)

The job then downloads both JDKs and performs a strict reproducible build comparison on them to indicate if they are identical.
"Platform" is required as reproducible build verification will vary based on platform (eg.Mac binaries need signing Signature removing before compare).

This is part of the epic #397

some part of the logic has been done in https://github.com/adoptium/ci-jenkins-pipelines/blob/master/tools/reproduce_comparison/compareMacOS.sh

Missing piece is how to get the cert on MacOS to set proper parameter https://github.com/adoptium/ci-jenkins-pipelines/blob/master/tools/reproduce_comparison/Jenkinsfile#L51
