Updates the use of weak references in the script-to-Java bridge for V8.

Currently, V8 uses weak references to the Java object owned by JObjectWrapper.
This is in contrast to JSC, which uses strong references in JObjectWrapper.
However, for the special-case where JObjectWrapper is used in JavaInstance in
WebCoreFrameBridge, JSC uses WeakJavaInstance to swap the strong references for
weak references.

This change updates the V8 version of JObjectWrapper to use strong references
to match the JSC version. To maintain the weak reference behavior where
JObjectWrapper is used in JavaInstance in WebCoreFrameBridge, V8 now make use of
WeakJavaInstance too. This requires changes to jni_npobject to call the
necessary methods on JavaInstance to swap the references when the object is
accessed.
