feat(cms): Allow background-images and split layout

Because:
* We want to allow background-images to be set by RPs as well as an optional split-layout which starts with email-first

This commit:
* Changes cmsInfo 'backgroundColor' to 'backgrounds.defaultLayout' to better describe what that field allows
* Pulls in shared 'backgrounds.splitLayout', 'backgrounds.splitLayoutAltText', updates headerBackground to 'backgrounds.header'
* Pulls in per-page 'splitLayout' boolean, passes this in for only email-first
* Removes loose background validity checks that are now handled in Strapi via regex
* Adds 3 initial background images to be used
* Adds CSS for new split layout

closes FXA-12188
