Deprecate ObjectSpace._id2ref

Browse Source 
[Feature #15408]

Matz decided to deprecate it for Ruby 2.6 or 2.7 but that never
actually happened.

Given the object_id table is a contention point for Ractors
it seems sensible to finally deprecate this API so we can
generate and store object ids more efficiently in the future.
