Class exception for each metadata module + handler to map on graphql
error
TODO left :
- find a way to call handler on auto-resolvers nestjs query (probably
interceptors)
- discuss what should be done for pre-hooks errors
- discuss what should be done for Unauthorized exception
- Implemented dataloader package on metadata graphql server
- Implemented a dataloader for relation metadata module

**Context**
cf. feature request
[#4597](https://github.com/twentyhq/twenty/issues/4597)
Enables deletion of custom fields that aren't active nor of type
relation
Also
1. renamed a misnamed file
2. deleted redundant hook BeforeDeleteOneField as it seemed best to move
the logic to the resolver instead
**How was it tested?**
Did not write unit tests as code is to be migrated (discussed with
@Weiko).
Locally tested.
