Log and benchmark the workings of a single block and silence whatever logging that may have happened inside it (unless use_silence is set to false).
The benchmark is only recorded if the current level of the logger matches the log_level, which makes it easy to include benchmarking statements in production software that will remain inexpensive because the benchmark will only be conducted if the log level is low enough.

Silences the logger for the duration of the block.
