RFR: 8341452: Test runtime/cds/appcds/DumpRuntimeClassesTest.java from JDK-8324259 is failing [v5]

[Matias Saavedra Silva]

> DumpRuntimeClassesTest.java was added in [JDK-8324259](https://bugs.openjdk.org/browse/JDK-8324259) to verify that the newly added dummy call archived classes that are used at CDS runtime. This new test exposed a case where `JarVerifier` is used at CDS runtime while not being in the archive, so this patch performs a dummy call to `JarVerifier`. 
> 
> When using `-Xcomp`, the class `Manifest` is compiled which causes `JarVerifier` to be loaded. This does not occur in other modes since the constructor of `Manifest` doesn't create any instances of `JarVerifier`. The existing dummy call to `Manifest` doesn't load `JarVerifier` either, so a separate dummy call can be used to ensure it is loaded at dumptime. Now that there are multiple dummy calls, they are pulled out into a new method `make_dummy_calls()`. Verified with tier x-y tests.
