optimize buildFieldMapsFromFlatObjectMetadata usages (#16132)

This newly introduced util can be a bit expensive especially when done
recursively.
This PR improves that


File | Pattern Fixed | Impact
-- | -- | --
format-result.util.ts | Recursive array/object processing | N array
items → 1 call
format-data.util.ts | Recursive array processing | N array items → 1
call
process-nested-relations-v2.helper.ts | Duplicate call in call chain | 2
calls → 1 call
common-result-getters.service.ts | Per-record processing in array | N
records → 1 call
compute-relation-connect-query-configs.util.ts | Nested loop (entities ×
connect fields) | N×M calls → 1 call
