Silvan 61cab8878e feat(backend): state persisted objects (#9870)
This PR initiates the rework of Zitadel's backend to state-persisted
objects. This change is a step towards a more scalable and maintainable
architecture.

## Changes

* **New `/backend/v3` package**: A new package structure has been
introduced to house the reworked backend logic. This includes:
* `domain`: Contains the core business logic, commands, and repository
interfaces.
* `storage`: Implements the repository interfaces for database
interactions with new transactional tables.
  * `telemetry`: Provides logging and tracing capabilities.
* **Transactional Tables**: New database tables have been defined for
`instances`, `instance_domains`, `organizations`, and `org_domains`.
* **Projections**: New projections have been created to populate the new
relational tables from the existing event store, ensuring data
consistency during the migration.
* **Repositories**: New repositories provide an abstraction layer for
accessing and manipulating the data in the new tables.
* **Setup**: A new setup step for `TransactionalTables` has been added
to manage the database migrations for the new tables.

This PR lays the foundation for future work to fully transition to
state-persisted objects for these components, which will improve
performance and simplify data access patterns.

This PR initiates the rework of ZITADEL's backend to state-persisted
objects. This is a foundational step towards a new architecture that
will improve performance and maintainability.

The following objects are migrated from event-sourced aggregates to
state-persisted objects:

* Instances
  * incl. Domains
* Orgs
  * incl. Domains

The structure of the new backend implementation follows the software
architecture defined in this [wiki
page](https://github.com/zitadel/zitadel/wiki/Software-Architecturel).

This PR includes:

* The initial implementation of the new transactional repositories for
the objects listed above.
* Projections to populate the new relational tables from the existing
event store.
* Adjustments to the build and test process to accommodate the new
backend structure.

This is a work in progress and further changes will be made to complete
the migration.
