Fix format result (#18975)
For a field that is not a relation and not a composite, there is no
legitimate reason to recurse into a plain object value.
The only cases where recursion makes sense are:
- Relations, the value is a nested entity record (handled at line 149)
- Composite fields - the value is being reassembled from flat columns
(handled at line 176+)
For everything else, a plain object value is just data
#### Perf testing
Compare findManyCompanies with a jsonField having same 20-level nested
value (cf quote)
