Fix ALTER TABLE .. ENABLE/DISABLE TRIGGER recursion
More precisely, correctly handle the ONLY flag indicating not to
recurse. This was implemented in 86f575948c77 by recursing in
trigger.c, but that's the wrong place; use ATSimpleRecursion instead,
which behaves properly. However, because legacy inheritance has never
recursed in that situation, make sure to do that only for new-style
partitioning.
I noticed this problem while testing a fix for another bug in the
vicinity.
This has been wrong all along, so backpatch to 11.
