Improve organisation of site background options #63096
Description
Extracted from #62752 as a smaller step forwards.
In global styles background options are a bit dis-oraganised and in the case of background image, tricky to find. This can be addressed by adding a 'Background' section which collates both options.
The background color option can continue to live in the Color section as it does today.
