Enforce coding style via clang-format

We tried that two years ago, but clang-format did not support

x(
  a,
  b
)

back then.

A configuration was added in #7240, now we need to reformat everything and run it on CI 😉

I really like the closing-bracket-on-same-indentation feature.

Don't we have this now?

[chriseth]

No, still a missing feature in clang-format.
