Make sure that runtime/benchmarks are dry-run in CI tests (#8330)

Ensure that `-Dbench.compileOnly` system property is correctly forwarded to the benchmarks' runner. So that in the CI Engine tests, benchmarks are *dry run*.

# Important Notes
- Fixes dry run benchmarks in Engine Test Action
- Fixes Engine Benchmark Action

-### Getting Set Up (JVM)
-
-In order to properly build the `runtime` component, the JVM running SBT needs to
-have some dependency JARs available in its module path at startup. To ensure
-they are available, before running any compilation or other tasks, these
-dependencies should be prepared. To do so, run the following command in the
-repository root directory:
-
-```bash
-sbt bootstrap
-```
-
-It is preferred to not run this command from the sbt shell, but in batch mode,
-because SBT has to be launched again anyway to pick up these JARs at startup.
-
-Bootstrap has to be run only when building the project for the first time
-**and** after each change of Graal version.
