Extract field metadata build out of object metadata build (#14763)

# Introduction

Extracting the legacy fields build and dispatch out of the object one to
follow the generic flat entity build, also update caches entries for
object

## Main tasks
- flat field map cache
- flat field builder
- refactored the dispatch matrix to return flat entity maps instead of
flat entity arrays
- orchestrator aggregator
- removing legacy code
- making universal identifier aka standardId of standard field for
custom object deterministically dynamic
- perfs debug logs for v2

## TODO
- [x] Refactor the generic entity builder to be dependency flat maps in
order to main foreign keys list in flat parent
- [x] Refactor the flat object metadata to contain the array of related
fields and avoid costy find object fields
- [ ] Improve the create field handler to handle multiple field at once
- [ ] Refactor the dispatch to embbed the comparison
- [ ] Improve perf by extracting from elements out of existing
- [ ] Fix the labelIdentifierId validators on object before field
creation ( integ tests are in failing mode )

## Debug logs snippet

[Runner] Transaction execution: 23.434ms
[Runner] Cache invalidation: 316.662ms
[Runner] Total execution: 340.767ms
```
As you can see cache invalidation is way to long, we could replace the
cache by the optimistic in the end
