Fix edit user email bug in API (#36068)

Follow #36058 for API edit user bug when editing email.

- The Admin Edit User API includes a breaking change. Previously, when
updating a user with an email from an unallowed domain, the request
would succeed but return a warning in the response headers. Now, the
request will fail and return an error in the response body instead.
- Removed `AdminAddOrSetPrimaryEmailAddress` because it will not be used
any where.
