Refactor CLUSTER and REINDEX grammar to use DefElem for option lists

Browse Source 
This changes CLUSTER and REINDEX so as a parenthesized grammar becomes
possible for options, while unifying the grammar parsing rules for
option lists with the existing ones.

This is a follow-up of the work done in 873ea9e for VACUUM, ANALYZE and
EXPLAIN.  This benefits REINDEX for a potential backend-side filtering
for collatable-sensitive indexes and TABLESPACE, while CLUSTER would
benefit from the latter.
