Add num_done counter to the pg_stat_checkpointer view.
Checkpoints can be skipped when the server is idle. The existing num_timed and
num_requested counters in pg_stat_checkpointer track both completed and
skipped checkpoints, but there was no way to count only the completed ones.
This commit introduces the num_done counter, which tracks only completed
checkpoints, making it easier to see how many were actually performed.
Bump catalog version.
