RFR: 7124527: [macosx] SwingSet2, label is not read by VoiceOver when focus is on textfield for Internalframe and Table demo. [v2]

[Abhishek Kumar]

> In SwingSet2, few label components are not set for textfield component in InternalFrame and Table demo and due to this VoiceOver doesn't announce the label along with the textfield value. Added a fix for that and verified in SwingSet2.
> 
> Apart from that for Selection mode combobox and Autoresize combobox, VoiceOver doesn't announce the combobox panel details along with combobox current item. 
> 
> Although the bug doesn't report this but in Slider demo it is observed that VoiceOver announces the slider value and panel details together.
> 
> So, added a fix similar to slider demo for combobox in tabledemo.
