Designer: Added ability to mark a node inline for styling

Description

In Figma we often build components from smaller components. In some cases those are actual implemented components, like a Button, but sometimes they are just convenience for construction in Figma.

The inline configuration option added to a node here allows us to mark a component as a construction utility and "inline" it into the components where it's used for style processing. The concrete example of this is a Label component which has the label text node and a required indicator node. It's unlikely we will write an actual Label component, rather that this is just an attribute or slot of a handful of implemented components. We can now mark that inline and components like a Text Filed, Select, etc. will be able to process styling for the label elements.

The alternative is that the instance in Figma is an actual published component, but we don't have the ability to detect that full list, so we assume that they are as this is more common.

Test Plan

Tested in CLI.
