[FIX] prefetch issues on computed fields (#18799)

When deciding to prefetch records (getting records from the cache with no value
for the field being fetched), if the field was computed `determine_value` would
just get all records, not limited by the normal prefetch limit; for large
recordsets this would generate gigantic prefetch lists for records we may not
need at all.

Fix by applying the `PREFETCH_MAX` limit to records from the cache as is done
in `_prefetch_field`.
