Report index vacuum progress.

Browse Source 
This commit adds two columns: indexes_total and indexes_processed, to
pg_stat_progress_vacuum system view to show the index vacuum
progress. These numbers are reported in the "vacuuming indexes" and
"cleaning up indexes" phases.

This uses the new parallel message type for progress reporting added
by be06506e7.

Bump catversion because this changes the definition of
pg_stat_progress_vacuum.
