TS/JS: Export object based classes on entry (#7822)

* TS/JS: Export object based classes on entry

Along with the non object ones, for consistency. This is a regression
introduced recently.

Before:
 `export { UpdateSettingsRequest } from './worker/update-settings-request.js';`

Now:
 `export { UpdateSettingsRequest, UpdateSettingsRequestT } from './worker/update-settings-request.js';`

* only export object based classes for structs

Enums are not elegible.
