Feature request: Implement `#ui2#cl_json=>raw_to_string`

[HOUNDmx]

Hi 👋🏼

It would be super nice to have that method available to use.

Use case:

• Handling a json payload in rawstring format, "stringify" it without the use of "deserialize", and pin-point to specific properties of that json with the use of the generate method + /ui2/cl_data_access=>create.

Found a workaround, but having this would reduce the size of the code by a lot

also string_to_raw

[larshp]

can you help writing a few basic testcases for the method?

[HOUNDmx]

yeah why not, let's give it a go
