Add pg_stat_wal statistics view.
This view shows the statistics about WAL activity. Currently it has only
two columns: wal_buffers_full and stats_reset. wal_buffers_full column
indicates the number of times WAL data was written to the disk because
WAL buffers got full. This information is useful when tuning wal_buffers.
stats_reset column indicates the time at which these statistics were
last reset.
pg_stat_wal view is also the basic infrastructure to expose other
various statistics about WAL activity later.
Bump PGSTAT_FILE_FORMAT_ID due to the change in pgstat format.
Bump catalog version.
