tools/codeformat.py: Add verbose option to pass to uncrustify and black.

This adds a new command line option `-v` to `tools/codeformat.py` to enable
verbose printing of all files that are scanned.

Normally `uncrustify` and `black` are called with the `-q` option so
setting verbose suppresses the `-q` option and on `black` also enables the
`-v` option which makes it print out all file names matching the filter
similar to how `uncrustify` does by default.
