Refactor code of pg_stat_get_wal() building result tuple
This commit adds to pgstatfuncs.c a new routine called
pg_stat_wal_build_tuple(), helper routine for pg_stat_get_wal(). This
is in charge of filling one tuple based on the contents of
PgStat_WalStats retrieved from pgstats.
This refactoring will be used by an upcoming patch introducing
backend-level WAL statistics, simplifying the main patch. Note that
it is not possible for stats_reset to be NULL in pg_stat_wal; backend
statistics need to be able to handle this case.
