Add border to root level of global styles

[carolinan]

What problem does this address?

If theme.json sets a broder style on the body, the user can not change or remove this border using global styles.

What is your proposed solution?

Add border settings to root level of global styles

@WordPress/gutenberg-design Is there any interest in adding this to the Site Editor Styles sidebar? I don't see it being mentioned in overview issues or similar.

Do you mean here, among typography, colors, layout?

If yes, my instinct is to only keep the most high value global items there, and if it only sets the border on the body element, it seems to put a great deal of emphasis to something you would style in Blocks in most other cases. I know that Saxon has explored some changes to the Global Styles IA in #47348 and #47369, the latter notably having an "Elements" category that could potentially hold a "body" element.
