Refactor object metadata service (#8123)

## Context
ObjectMetadataService became quite large and handles too many
responsibilities. I'm trying to refactor a bit this part in preparation
of a larger work that will combine object-metadata services and
sync-metadata logic

- Created a STANDARD_OBJECT_ICONS that can be reused in relation
creation to refer to a standard object icon.
- Created a STANDARD_OBJECT_FIELD_IDS that can be used with an object
name to get its standard field ids.
- Moved migration, record and relation creations to dedicated services,
refactored to improve performances and readability
- Refactored some validation logic
