Gets an instance of a type that may be used to perform operations on a FrozenDictionary<TKey,TValue>
using a TAlternateKey as a key instead of a TKey.

The alternate type of a key for performing lookups.
The created lookup instance when the method returns true, or a default instance that should not be used if the method returns false.
true if a lookup could be created; otherwise, false.
This instance must be using a comparer that implements IAlternateEqualityComparer<TAlternate,T> with TAlternateKey and TKey. If it doesn't, the method will return false.
