Similar to https://github.com/llvm/llvm-project/pull/82416, but it allows you to filter full directories without the need of a complex regex in `-source-filter`

For example:
```
python run-clang-tidy.py -fix -p \"build\" -j 12 -directory-filter build -directory-filter bin -directory-filter tests
```

To filter out `bin`, `build` and `tests` folders
