Additional checks were recently added to ICC_Profile (see [JDK-8347377](https://bugs.openjdk.org/browse/JDK-8347377)). As a result, objects previously stored as valid profiles may now throw an IllegalArgumentException during serialization. Discussion about serialization was started in https://github.com/openjdk/jdk/pull/23044 but it seems at the end non-serialization related check was [verified](https://github.com/openjdk/jdk/pull/23044/commits/a5201b5f353e8957a1274261372496768edbc7a2). =(

The patch itself is simple, but I found that we do not have good test coverage in this area. So I added two tests to cover all possible variants specified by the serialization spec.
