[ColorPicker]Store color history in a separated file (#23146)

Browse Source 
* [ColorPicker] Store color history in a separated file

* ColorPicker] Separated file for color history: use the list from the settings.json if there is no ColorHistory.json file (preventing loss of existing color history)

* Fix case when there is no history saved or no settings file at all.
