RFR: 8353298: AOT cache creation asserts with _array_klasses in an unregistered InstanceKlass

[Ioi Lam]

The assert in `Klass::remove_java_mirror()` is too narrow. When creating the AOT cache, it's possible to see two types of Klasses that do not have a Java mirror:

- Unregistered classes (a cached class to be loaded by a custom class loader in the production run)
- An array type of an unregistered class

I have relaxed the assert to accept both conditions
