RFR: 8311990: Two JDI tests may interfere with each other [v3]

[Alex Menkov]

> "Attach fails" scenarios (debuggee starts listening and debugger is expected to fail trying to attach) sometimes interfere with other JDI tests (so JdwpNetProps.java test or other JDI test or both fail).
> The fix disables the scenarios to remove noise in the CI.
