Refactor parsing rules for option lists of EXPLAIN, VACUUM and ANALYZE

Those three commands have been using the same grammar rules to handle a
a list of parenthesized options.  This refactors the code so as they use
the same parsing rules, shaving some code.  A future commit will make
use of those option parsing rules for more utility commands, like
REINDEX and CLUSTER.
