Add ODS logger and use it during init (#4969)

## Change
The user settings (and then group policy) initialization happen before
we get the file logger set up. To be able to see into what is happening
there more easily, this change creates a logger that uses
`OutputDebugString` and uses it during the initial file logger creation.
