Summary [css-ui] Unexpose attachment and borderless-attachment appearance values

borderless-attachment should be restricted behind useSystemAppearance. Although I wonder if we could make this work through appearance: auto + borderless attribute, so we can stop exposing the CSS value altogether, though that would require consumers of <attachment> + appearance: borderless-attachment to change to <attachment borderless>. attachment is implemented via appearance: auto, so we shouldn't need to keep the CSS value around.
