[lworld] RFR: 8377576: [lworld] JVM_CopyOfSpecialArray does not handle all inputs correctly

[Paul Hübner]

Hi all,

`Arrays.copyOf` and `Arrays.copyOfRange` internally use the same function, `JVM_CopyOfSpecialArray`. While they both copy arrays, there are some semantic differences in parameter checking and exception throwing between the two that `JVM_CopyOfSpecialArray` is unable to differentiate. This patch includes:
* Separate error condition checking and exception throwing per method.
* New test cases for each method.

Testing: tier 1.
