RFR: 8330647: Two CDS tests fail with -UseCompressedOops and UseSerialGC/UseParallelGC [v5]

[Calvin Cheung]

> The following two tests contain `@requires vm.cds.write.archived.java.heap` which implies `UseG1GC && UseCompressedClassPointers`
> 
> cds/appcds/cacheObject/ArchiveHeapTestClass.java
> cds/serviceability/ReplaceCriticalClassesForSubgraphs.java
> 
> The tests would fail if options conflicting with `vm.cds.write.archived.java.heap` are specified via the ` -Dtest.cds.runtime.options` property because the options would be added after the `@require` check.
> 
> A fix is to check if the ` -Dtest.cds.runtime.options` property contains non-null value and throws a `SkippedException`.
> 
> Update:
> The checking of the ` -Dtest.cds.runtime.options` property is now performed in VMProps.java.
