Create a single LauncherSession for invocations of JUnitPlatformProvider#863

Prior to this commit, `JUnitPlatformProvider` created multiple `LauncherSessions` for some executions, for example when `forkTestSet` was `null` or when rerunning failed tests. This caused registered `LauncherSessionListeners` registered via `ServiceLoader` on the JUnit Platform to be called multiple times. As they are intended to set up and tear down resources, this had the potential of unnecessarily slowing down test execution.

Hey @marcphilipp Thanks for the PR! Would you call this a bugfix (as not intended to use this way) or enhancement? |

I think it's not strictly a bug so I would call it an enhancement. 🙂 |
