feat: introduce Grid as a new question type

[Koc]

Closes #2606

🚧 Development still in progress. This is reopening of the #2924 but pushed to upstream instead of my fork.

I'm trying to reuse already existent Option entity and corresponding UI components by adding extra column optionType=row|column. Why?

• as rows/columns can be renamed - we need to store their ids. So I've just reused already existent mechanism
• we should have possibility to reorder rows/columns. Already existent UI components for options allow us to do that

✔️ Implemented

🔍 Various input types

Radio

Checkbox

Text/Number

🔍 Question management

Create new field with nested select menu

Manage rows and columns

🔍 Results storing and rendering

@nimishavijay @jancborchardt please suggest how to display results summary

I guess we can show table with counters for radio/checkbox grid cell type. But what to do for a number/text values?

FYI @nimishavijay I've applied almost all of your suggestions. Please check or even feel free to commit to my branch

Also does anybody know how to export this type of the question to xlsx files?

But what to do for a number/text values?

@Koc I'm still against allowing free text answers for the grid questions. It makes things much more complex than needed and I didn't see any other form solution providing this.

[Koc]

@Chartman123 I agree that free text answers is indeed can be an overkill and it will be removed.

But worth to mention that the main reason I started working on the Grid field type is our need to collect numeric values in matrix form. I've added checkboxes and radios to make it more universal, but without numeric input, the field would have no real value for our use cases.

We are using that for resource allocation tables, workload estimations, etc
