psql: Improve tab completion for COPY option lists.

Previously, only the first option in a parenthesized option list was
suggested by tab completion. This commit enhances tab completion for
both COPY TO and COPY FROM commands to suggest options after each
comma.

Also add completion for HEADER and FREEZE option value candidates.
