Show shadows in the inspector that don't use the utility fn

STR

Example 1

1. Insert a view
2. give it a shadow. Note the utility function
3. remove that shadow and replace it with a custom shadow, eg boxShadow: '0px 3px 5px 1px rgba(0,0,0,.25)'

Expected: shows up in in the inspector. Observed: it does not. Also applies to multiple shadows

Note: we originally introduced the utility fn because border would affect the layout and 'move' the box. Same with margin and why we didn't support it. This is no longer an issue, so I believe we could have border set real border, boxShadow a real box shadow, and retire the utility fn.
