feat: consolidate comments from nested levels of schemas

[ad-world]

DX-592

This is a PR that adds functionality to consolidate comments when they are present in different schemas that refer to each other.

For example.

/** 
@example 123
*/
const EnterpriseIdString = t.string;

const Enterprise = t.type({
    /** The Enterprise ID */
    id: EnterpriseIdString
})

Previously, the example would get stripped from the generation since we saw the second comment and used it to overwrite the first one. This PR ensures that we don't lose that information.
