JNIGlobalRef: Add copy-ctor, move-ctor and equality operations

Goal is to utilize JNIGlobalRef as a first class shared jobject instance
without the need to use std::shared_ptr<JNIGlobalRef>.

+++

Efficiency and functionality: Add copy-ctor, move-ctor

- Allow a JNIGlobalRef to be shared by creating copies
  with a 'NewGlobalRef(..)'.

- Allow JNIGlobalRef to be moved by 'nulling' the source jobject

+++

Functionality: Add equality operations

- test inner jobject via 'IsSameObject(..)'
