scripts/ci: implement code style

[sophiekovalevsky]

This is a starting point thinking that maybe in the future other hardware engineers may want to contribute. Why if we don´t start to verify that every changes are made be compliant with some code format. Currently, I tested this only for the pc application but I can imagine that can be extrapolated to the firmware side.

@jankae, what do you think?

Seems like clang-format is not able to use c++17 though

I am not too familiar with automatic code format checks, will look into it after next week
