Inline trivial wrapper recipes into ReproducibleBuilds composite

Removes the standalone AddSourceEncodingProperty and
UpgradePluginVersionsForReproducibleBuilds wrappers and inlines their
content directly in ReproducibleBuilds. ReproducibleBuildsTest still
exercises the full behavior end-to-end.

-description: >-
-  Upgrades core Maven plugins to the minimum version known to honor `project.build.outputTimestamp`,
-  per the [Maven Reproducible Builds guide](https://maven.apache.org/guides/mini/guide-reproducible-builds.html).
-  Plugins are only upgraded; older versions ignore `outputTimestamp` and produce non-reproducible artifacts.
