Support verbose logging in script `regen-test-files`.
Add support for option `-v`, `--verbose` to script
`test/utils/regen-test-files`. When enabled, set logging level to
`DEBUG` to log more information.
Also add some DEBUG-level logging statements for I/O operations
performed by the script.
Test: Run `test/utils/regen-test-files -m -v` and check that there are
no changes among the generated files
