In this PR:
## Improve recompute metadata cache performance. We are aiming for
~100ms
Deleting relationMetadata table and FKs pointing on it
Fetching indexMetadata and indexFieldMetadata in a separate query as
typeorm is suboptimizing
## Remove caching lock
As recomputing the metadata cache is lighter, we try to stop preventing
multiple concurrent computations. This also simplifies interfaces
## Introduce self recovery mecanisms to recompute cache automatically if
corrupted
Aka getFreshObjectMetadataMaps
## custom object resolver performance improvement: 1sec to 200ms
Double check queries and indexes used while creating a custom object
Remove the queries to db to use the cached objectMetadataMap
## reduce objectMetadataMaps to 500kb

We used to stored 3 fieldMetadataMaps (byId, byName, byJoinColumnName).
While this is great for devXP, this is not great for performances.
Using the same mecanisme as for objectMetadataMap: we only keep byIdMap
and introduce two otherMaps to idByName, idByJoinColumnName to make the
bridge
## Add dataloader on IndexMetadata (aka indexMetadataList in the API)
## Improve field resolver performances too
## Deprecate ClientConfig
Fixes an infinite loop introduced by #12371
An infinite loop was triggered when there was an error when fetching the
client config.
Cause of the bug: `isLoadedOnce` wasn't set to true when catching an
error in `useClientConfig`.
This effect then created an infinite loop inside
`ClientConfigProviderEffect` because `fetchClientConfig` updated
`clientConfigApiStatus.isLoading` but not `isLoadedOnce`.
```typescript
useEffect(() => {
if (
!clientConfigApiStatus.isLoadedOnce &&
!clientConfigApiStatus.isLoading
) {
fetchClientConfig();
}
}, [
clientConfigApiStatus.isLoadedOnce,
clientConfigApiStatus.isLoading,
fetchClientConfig,
]);
```
Changes for performance improvement.
The primary improvements include replacing GraphQL queries with
REST-based client configuration fetching and making the client config
non render-blocking
