Add indisreplident to fields refreshed by RelationReloadIndexInfo()

RelationReloadIndexInfo() is a fast-path used for index reloads in the
relation cache, and it has always forgotten about updating
indisreplident, which is something that would happen after an index is
selected for a replica identity.  This can lead to incorrect cache
information provided when executing a command in a transaction context
that updates indisreplident.

None of the code paths currently on HEAD that need to check upon
pg_index.indisreplident fetch its value from the relation cache, always
relying on a fresh copy on the syscache.  Unfortunately, this may not be
the case of out-of-core code, that could see out-of-date value.
