JEP471 sets system property according to the command line option value

JEP471 sets system property according to the command line option value

--sun-misc-unsafe-memory-access=value which is expected to be "allow", "warn", "debug" or "deny";
Set a system property sun.misc.unsafe.memory.access with the value specified via --sun-misc-unsafe-memory-access=value.

Verified locally that sun/misc/UnsafeMemoryAccessWarnings.java passes.

I removed the closes keyword. #19583 shouldn't be closed until the test is unexcluded.

Sure, the un-exclude PR is in draft currently

• JDK23 unexcludes sun/misc/UnsafeMemoryAccessWarnings.java adoptium/aqa-tests#5371

I do find it a bit odd that the args aren't consumed in java.c like the rest (ie. --enable-native-access, --add-modules, ...)
