This is wip workaround for https://github.com/servo/servo/issues/10841
Adds ``servo-tidy.toml`` with configs and ignored dirs, files and packages.
This will allow to set custom configuration per repo.
It's an example how could config file looks like.
I want opinion on that, if this is right approaches and how to improve it.
