When EnableReadDeepClone is true HashSet method Remove fails

## Description

When you store a HashSet object in MemoryCache and retrieve the object when you are trying to remove an item from the collection operations fail.

### Steps to Reproduce

1. Create a HashSet with 2 items
2. Store it in MemoryCache with EnableReadDeepClone = true
3. Retrieve it from Cache
