We've introduced in PR #4373 standard ids to be able to rename standard
fields and objects.
Fields part was working properly, but objects part was not yet
implemented.
This PR is adding the missing parts to make it work.
This PR is dropping the column `targetColumnMap` of fieldMetadata
entities.
The goal of this column was to properly map field to their respecting
column in the table.
We decide to drop it and instead compute the column name on the fly when
we need it, as it's more easier to support.
Some parts of the code has been refactored to try making implementation
of composite type more easier to understand and maintain.
Fix#3760

**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.
