Add the 'valuePicker' functionality to the colorpicker. This is useful
for editors to have a series of defaults. A similar configuration worked
in the past based on 'select' wizard.

Example TCA from styleguide master input_37:
    'config' => [
        'type' => 'input',
        'renderType' => 'colorpicker',
        'size' => 10,
        'valuePicker' => [
            'items' => [
                [ 'blue', '#0000FF', ],
                [ 'red', '#FF0000', ],
                [ 'typo3 orange', '#FF8700', ],
            ],
        ],
    ],
