pg_stat_statements: Add wal_buffers_full
wal_buffers_full tracks the number of times WAL buffers become full,
giving hints to be able to tune the GUC wal_buffers.
Up to now, this information was only available in pg_stat_wal. With
this field available in WalUsage since eaf502747bac, exposing it in
pg_stat_statements is straight-forward, and it offers more granularity
at query level.
pg_stat_statements does not need a version bump as one has been done in
commit cf54a2c00254 for this development cycle.
