cool#7406: Refactor Calc->getPartInfo & use JsonWriter.

Indeed this seems unrelated to the task. But grid in Impress requires to add new properties to "getPartInfo (impress)".
When i checked the code, i saw that we use getPartInfo's result (on server side) like it's a text instead of JSON. So we'll refactor that part.
Touching that part requires also touching some other shared functions on COOL side. And those changes also required adding new props here.

We have been fetching this data (without adding new properties) one by one. We now will be able to fetch the whole part's data at once.

This commit also uses JsonWriter class.
