Alexander Korotkov 29854ee8d1 Support for unnest(multirange) and cast multirange as an array of ranges 
It has been spotted that multiranges lack of ability to decompose them into
individual ranges.  Subscription and proper expanded object representation
require substantial work, and it's too late for v14.  This commit
provides the implementation of unnest(multirange) and cast multirange as
an array of ranges, which is quite trivial.

unnest(multirange) is defined as a polymorphic procedure.  The catalog
description of the cast underlying procedure is duplicated for each multirange
type because we don't have anyrangearray polymorphic type to use here.

Catversion is bumped.
