Reorganize color picker from common styles

• Type: Feature Request
• Status: Aligned with Roadmap
• Resolution: Unresolved
• Affects Version/s: Master
• Fix Version/s: None
• Component/s: Pages > Page Editor
• Labels: None

Right now, we fill the color picker with all the token of type colors of the token definition. This could result in what we have right now, that we have a lot of similar or equal colors.

It would be nice to have some way to determine which colors we want to apper in the color picker of the content pages, maybe an extra property in the JSON definition like:

themeColor: true
