This new query is designed to become the canonical source of information regarding whether a declaration is available to use in a given `AvailabilityContext`. It should be adopted as the foundational building block for all other queries that answer more specific questions about the availability of a specific delcaration. The implementation of this query has been copied from a variety of sources which should eventually be deleted once the new query has been fully adopted. NFC.
