feat: project v2beta resource API (#9742)

# Which Problems Are Solved

Resource management of projects and sub-resources was before limited by
the context provided by the management API, which would mean you could
only manage resources belonging to a specific organization.

# How the Problems Are Solved

With the addition of a resource-based API, it is now possible to manage
projects and sub-resources on the basis of the resources themselves,
which means that as long as you have the permission for the resource,
you can create, read, update and delete it.

- CreateProject to create a project under an organization
- UpdateProject to update an existing project
- DeleteProject to delete an existing project
- DeactivateProject and ActivateProject to change the status of a
project
- GetProject to query for a specific project with an identifier
- ListProject to query for projects and granted projects
- CreateProjectGrant to create a project grant with project and granted
organization
- UpdateProjectGrant to update the roles of a project grant
- DeactivateProjectGrant and ActivateProjectGrant to change the status
of a project grant
- DeleteProjectGrant to delete an existing project grant
- ListProjectGrants to query for project grants
- AddProjectRole to add a role to an existing project
- UpdateProjectRole to change texts of an existing role
- RemoveProjectRole to remove an existing role
- ListProjectRoles to query for project roles

# Additional Changes

- Changes to ListProjects, which now contains granted projects as well
- Changes to messages as defined in the
[API_DESIGN](https://github.com/zitadel/zitadel/blob/main/API_DESIGN.md)
- Permission checks for project functionality on query and command side
- Added testing to unit tests on command side
- Change update endpoints to no error returns if nothing changes in the
resource
- Changed all integration test utility to the new service
- ListProjects now also correctly lists `granted projects`
- Permission checks for project grant and project role functionality on
query and command side
- Change existing pre checks so that they also work resource specific
without resourceowner
- Added the resourceowner to the grant and role if no resourceowner is
provided
- Corrected import tests with project grants and roles
- Added testing to unit tests on command side
- Change update endpoints to no error returns if nothing changes in the
resource
- Changed all integration test utility to the new service
- Corrected some naming in the proto files to adhere to the API_DESIGN
