changefeedccl: disable physical plan debug persistence

[dt]

Mitigation for #126083.

Release note (ops change): Some debugging-only information about physcial plans is no longer collected in the system.job_info table for changefeeds due to it having the potential to grow very large.

Epic: none.

We could consider doing this for PCR as well.

We could consider doing this for PCR as well.

My thinking is this goes to 23.1 and 23.2, but for 24.x onward #126084 is the answer, which will cover releases in which PCR is GA.

But we can always open another PR for PCR specifically if we change our mind.

TFTR!

You might need to create your backport manually using the backport tool.
