[macosx] two JNI locals to delete in AWTWindow.m, CGraphicsEnv.m

        A JNI local is generally deleted when:

        1) the JNI method returns
        2) it's wrapped in PushLocalFrame/PopLocalFrame calls
        3) DeleteLocalRef is called

        The problem is that a JNI local can be created inside an endless message pump (then the 1st point doesn't work), or out of the push/pop block (2nd doesn't work). Then the only way to avoid its leaking is to delete it manually.

        (For instance, see JDK-8145984 where missed JNI locals caused memory leaks.)

        There're two more JNI locals to delete:

        - AWTWindow.m, sendEvent: platformWindow
        - CGraphicsEnv.m, displaycb_handle: graphicsEnv
