RFR: 8297342: make LOG=debug is too verbose

Mon Nov 21 14:20:21 UTC 2022

The `debug` level of make logging is not really useful, since it spits out a full expansion of all named param macro arguments and their values. 

With the NamedParamsMacroTemplate being stable for years, this is seldom useful, and the massive amount of logs drown out everything else.

We should move this debugging to the `trace` level.
