GH Actions: Add nightly job to run Classic cluster tests (#30572)

* GH Actions: Add nightly job to run Classic cluster tests

* Run tests as multi-jvm instead of multi-node

* Some minor adjustments

* Rename for clarity

* Use JDK 11

* Group some tests to reduce parallelism

* Allow to exclude multi-jvm tests using `-Dakka.test.names.exclude` property

* Exclude akka.cluster.Stress tests

* Move akka classic remoting job to nightly-builds workflow
