[Blocked by Scala 3 Bug] Implement Scala 3 recompilation token (#1805)

* Revert "Disable recompilation trigger functionality on Scala 3 completely due to bug scala/scala3#15976"

This reverts commit 2ab8bf4.

* use random token again. Waiting on usability fix for scala/scala3#18623 before merge

* CI workaround for scala/scala3#19745

* Due to Scala 3 bug scala/scala3#19745 remove `distage.plugins.{PluginDef,BootstrapPluginDef}` aliases on Scala 3
