[com_fields] Fix wrong render_class being applied to field value after 3.9.28 (#35559)

* Make a separate field for the value class

It's not good to apply the global render_class to the value. If you want a class for just the value, it should be a separate field.

* Language strings for the field value class

* Use value-specific class instead of render_class for the value

* Add field name as as part of the field class as well

* typo
