feat(): enable custom domain usage (#9911)

# Content
- Introduce the `workspaceUrls` property. It contains two
sub-properties: `customUrl, subdomainUrl`. These endpoints are used to
access the workspace. Even if the `workspaceUrls` is invalid for
multiple reasons, the `subdomainUrl` remains valid.
- Introduce `ResolveField` workspaceEndpoints to avoid unnecessary URL
computation on the frontend part.
- Add a `forceSubdomainUrl` to avoid custom URL using a query parameter
