Resizable Color Picker

### Description of the new feature / enhancement

The Color Picker window will be resizable or automatically resize to fit its contents. The widnoiws would remember its size and position.

### Scenario when this would be used?

All scenarios.

### Supporting information

When Window.ResizeMode="NoResize", it is often paired with SizeToContent="WidthAndHeight" for fixed-size dialogs. The SizeToContent property is not currently present in src/modules/colorPicker/ColorPickerUI/ColorEditorWindow.xaml.

Start with src/modules/colorPicker/ColorPickerUI/ColorEditorWindow.xaml and inspect the current window sizing settings, especially the missing SizeToContent property. Determine how the window should resize or fit its contents and how its size and position are retained. Done means the Color Picker window handles its contents, can be resized as intended, and restores its size and position.
