Correctly annotate things that are unused when logging is disabled.

bzbarsky-apple · bzbarsky-apple · commit 66050f5b056d · 2024-02-21T11:12:02.000-05:00
We don't seem to have very good CI coverage for the logging-disabled configurations. Also removes UNUSED_VAR and UNUSED_PARAMETER use in favor of the standard [[maybe_unused]]. Fixes project-chip#32113
