pgsql: Add long options to pg_resetwal and pg_controldata

Add long options to pg_resetwal and pg_controldata

We were running out of good single-letter options for some upcoming
pg_resetwal functionality, so add long options to create more
possibilities.  Add to pg_controldata as well for symmetry.

based on patch by Bossart, Nathan <bossartn@amazon.com>
