Preserve firing-on state when cloning row triggers to partitions

Browse Source 
When triggers are cloned from partitioned tables to their partitions,
the 'tgenabled' flag (origin/replica/always/disable) was not propagated.
Make it so that the flag on the trigger on partition is initially set to
the same value as on the partitioned table.

Add a test case to verify the behavior.

Backpatch to 11, where this appeared in commit 86f575948c.
