RFR 8158855: Fix remaining module dependences in java/lang

[Mandy Chung]

Hi Shura,

test/java/lang/Class/GetModuleTest.java
   This can use java.base/jdk.internal.misc.Unsafe instead.

Other @modules looks okay.

Regarding the executeTestJava change, if you drop the VM options, this test will only exercise the default launcher setting.  The hotspot nightlies depend on VM options to exercise different configurations.  I think many tests that launch a modular test will run into the same issue.  It’s not ideal to drop the VM options then.  One alternative is to have a new ProcessTool::executeModularTest that will take test.vm.opts and test.java.opts but dropping -limitmods, if any.
