Enable log-to-file configuration (#7918)

* Enable log-to-file configuration PR #7825 enabled parallel logging to a file with a much more fine-grained log level by default. However, logging at `TRACE` level on Windows appears to be still problematic. This PR reduced the default log level to file from `DEBUG` to `TRACE` and allows to control it via an environment variable if one wishes to change the verbosity without making code changes. * PR comments
