Fixed #36380 -- Deferred SQL formatting when running tests with --debug-sql.

Thanks to Jacob Walls for the report and previous iterations of this
fix, to Simon Charette for the logging formatter idea, and to Tim Graham
for testing and ensuring that 3rd party backends remain compatible.

This partially reverts d8f093908c.

Refs #36112, #35448.
