RFR: 8204168: Increase small heap sizes in tests to accommodate ZGC

[coleen.phillimore at oracle.com]

I included the serviceability-dev list for the jdi tests.  I don't think 
this change increases the heap for these tests enough to cause any 
problems, so I think this change is fine.
thanks,
Coleen
