## Problem description
During tests we found concurrency issues in the relational table
projections. Tests got flaky if a table (e.g. organization domains) had
too many foreign keys to tables which were projected by another handler.
## Resolution
The projections of the relational tables got merged into one handler to
enforce sequential reduction of events.

# Which Problems Are Solved
This PR implements relational table and repository interface for the
authorizations feature as described in
https://github.com/zitadel/zitadel/issues/10767
# How the Problems Are Solved
By
* adding new `zitadel.authorizations` and `zitadel.authorization_roles`
tables
* implementing the `AuthorizationRepository` interface to create,
update, query, and delete user authorizations and roles
* implementing `authorization_relational.go` projection to update
`zitadel.authorizations` and `zitadel.authorization_roles` tables based
on events
