pgsql: Remove ACLDEBUG #define and associated code.

Remove ACLDEBUG #define and associated code.

In the footsteps of aaf069aa3, remove ACLDEBUG, which was the only
other remaining undocumented symbol in pg_config_manual.h. The fact
that nobody had bothered to document it in seventeen years is a good
clue to its usefulness. In practice, none of the tracing logic it
enabled would be of any value without additional effort.
