Support cmake-format

[okainov]

It maybe not directly related, but usually people check native code with clang-format (this script) and cmake files with cmake-format. The tools have relatively similar interface and both of them don't support scanning folders :) While this scripts solves is for clang-format, it would be nice to have the similar wrapper on cmake-format.

Possible options:

• Completely different script/repo
• Integrate the possibility to run both tools from this script

I think latter will be useful for a lot of people, so there won't be the need to different wrappers and there can be one to rule them all.

I would first try to see if cmake-format cannot it himself, unlike clang-format, it is already coded in python, and the project is smaller, younger, so it's easier to add features to it.
