[PATCH v4 0/2] Subject: clang-format: fix rules to make the CI job cleaner

[Karthik Nayak <karthik.188@gmail.com>]

The clang-format CI job is currently cluttered due to too many errors being
reported. See some of the examples here:

* https://gitlab.com/gitlab-org/git/-/jobs/7854601948
* https://gitlab.com/gitlab-org/git/-/jobs/7843131109

So modify the clang-format with the following changes:
1. Modify the penalties for linebreaks to be more considerate towards
readability. The commit goes into detail explaining how/why.  
2. Align the macro definitions. This is something we follow to keep the macros
readable. 

I will still keep monitoring the jobs from time to time to ensure we can fine
tune more as needed, if someone see's something odd, do keep me in the loop.

Thanks

Changes over the previous version:
1. I made the example in the first commit message a bit clearer so it is easier
to understand.
2. Removed the third commit, since I was convinced that it is good as-is for now.
