More recreatable field names in FIELDS*

[Artyom Bologov]

What would be good for recursive and reproducible describe*/inspect* workflow is using the function that represents the field as the field name. E.g., use find-class instead of class-binding in (describe* 'nyxt:buffer):

From:
CLASS-BINDING     = #<NYXT:USER-CLASS NYXT:BUFFER>
To:
CL:FIND-CLASS     = #<NYXT:USER-CLASS NYXT:BUFFER>
