GROOVY-8067: Possible deadlock when creating new ClassInfo entries in the
cache
While I have been able to replicate the deadlock between
`GroovyClassValuePreJava7$Segment` and the `GlobalClassSet#add`, I have not
directly observed one between the `modifiedExpandos` and the `GlobalClassSet`,
but think that it would be good to isolate their reference processing too since
both lock in their operations.
