8365885: Clean up constant pool reflection native code

[liach]

When I was trying to reuse this constant pool reflection for assembly phase indy argument validation, I noted the JNI code has a lot of confusing arguments. In particular, the JVM_ConstantPoolGetSize is wrong because of argument confusion. We should remove the unused arguments to reduce confusion.
