RFR: 8268536: mark hotspot serviceability/dcmd tests which ignore external VM flags

[Igor Ignatyev]

Hi all,

could you please review the patch which adds `@requires vm.flagless` to `serviceability/dcmd/gc/RunFinalizationTest.java` and `serviceability/dcmd/compiler/CodeHeapAnalyticsParams.java` tests as they completely ignore external vm flags?

Thanks,
-- Igor
