Merged PR 2511: Adding stg_core__role and stg_core__user_role in staging

# Description

Adds Role and UserRole in staging, in dedicated tables.
Open to discussion if you want me to directly apply this at User table level instead of having them in staging as standalone tables. Otherwise, staying with this PR as is, next step would be to integrate these roles in unified_user and create a dedicated user_host table in intermediate
