RFR: 8281186: runtime/cds/appcds/DumpingWithNoCoops.java fails

[Calvin Cheung]

A simple fix to the test failure by specifying the heap sizes for most of the test cases.
Before the fix, if the MaxHeapSize is determined by the VM, the MaxHeapSize could become smaller
than the MinHeapSize or the InitialHeapSize which causing the failure.

Testing: CI tiers 1 - 4.
