DacFX does not generate the OBJECT_ID property for CREATE USER

- SqlPackage or DacFx Version: 16.18089.0
- .NET Framework (Windows-only) or .NET Core: 4.8.09032
- Environment (local platform and source/target platforms): (local)

**Steps to Reproduce:**

1. Create a project, create a user object having the OBJECT_ID option in the EXTERNAL flavour of the principal.
2. Build the project (Works)
3. Create a deployment script for the database and inspect the script. => The script will omit the OBJECT_ID part.

The ScriptDom implemented the parsing, thought he DacFX does not have to logic so far.

**Did this occur in prior versions? If not - which version(s) did it work in?**

(DacFx/SqlPackage/SSMS/Azure Data Studio)

Start by reproducing the CREATE USER case in DacFx or SqlPackage using an external principal with OBJECT_ID, then inspect the generated deployment script. Compare the project definition with the script output and use ScriptDom as the parsing reference; done means the OBJECT_ID option is preserved in the deployment script.
