[lworld] RFR: 8375332: [lworld] JDI tests timeout with -XX:+UseCompactObjectHeaders on windows-x64

[Alex Menkov]

TestScaffold uses test arguments as additional options for debuggee process.
Options like `-XX:+PrintInlineLayout',  `-XX:+PrintFlatArrayLayout` can cause significant debuggee output before TestScaffold connect to the debuggee and start to read it output. As a result internal output buffer fills and debuggee process hungs.
The fix removes extra arguments used for experiments at test development.
