[Order / Products details] Adjust Variable product lists to display selected Attributes as `Any`

[ThomazFB]

Context

All Variable products must contain attributes to define it Variations, if a Variation doesn't have a valid Attribute selected, Woo Core and our apps consider this as an Any Attribute. E.g. if you select no color for your T-shirt as a variable product, the Any color will be set.

The issue

As highlighted in #5860, WCAndroid doesn't display the Any selection scenario, but iOS does. In order to achieve platform parity, we want to adjust that for every Product lists inside our app that displays the Attribute details.

Example

As noted in #5860 (comment), Core doesn't show “Any” at all. So we still have to discuss what's the right way to do it.

I'll move this out of the Order Creation project for now but we'll keep an eye on it on the Eagle board.
