RFR: 8271328: User is able to choose the color after disabling the color chooser. [v2]

[Abhishek Kumar]

> The proposed solution for this defect is to check the color chooser enabled state. If it is disabled then disable all the components (spinner, textfield etc.) in panel and don't process the mouse event when user click on a color triangle or color wheel.
