Determine next log file number from directory on first run
Backport of #41375 to 6.0
Restores file logging behavior after the app restarts multiple times in a single day.
Description
Fixes #41326
Customer Impact
Without this patch, an app that restarts multiple times per day (due to CI or app crashes) will stop logging w3c logs until the next day.
Regression?
Risk
This code is called on every web request, but the logic to determine the first filename only runs once per app start, and has guards when parsing the highest log number from the existing files on disk.
Verification
Packaging changes reviewed?
