Add color schemes to themes

Theme developers can now add color schemes to themes. This update adds clarity and flexibility to the theme editing experience by allowing theme-defined and merchant-defined color schemes, adding a visual preview that enables merchants to more easily and predictably update theme colors, and allowing merchants to implement theme changes at the global, section, and block level within their theme.

A solution which will enable theme developers to specify how to migrate merchants’ theme data during the update process when introducing architecture changes (ex: changing scope of settings, modifying schema structure in other ways etc.) will be available later this summer.
