LinkedMultiValueMap's copy constructor takes a shallow copy of the given Map, reusing the List values there. In order to fix #17777 but also generally, we should allow for taking a deep copy as well.

I've added public clone() and deepCopy methods to LinkedMultiValueMap as of 4.2, applied within DefaultSubscriptionRegistry but also available for any other use.
