[8.18] [Build] Add support for publishing to maven central (elastic#128659) (elastic#129080)

* [Build] Add support for publishing to maven central (elastic#128659)

This ensures we package an aggregation zip with all artifacts we want to publish to maven central as part of a release.
Running zipAggregation will produce a zip file in the build/nmcp/zip folder. The content of this zip is meant to match the maven artifacts we have currently declared as dra maven artifacts.

(cherry picked from commit 3420831)
