Revert "add a .clang-format file (#9154)" (#9172)

I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.

I have a solution but it require creating a new commit at the merge base for each conflicting PR and merging it into develop.

I don't think blowing up all PRs is worth for now, maybe if we can coordinate this for V3 let's say.

This reverts commit 0d11331d18.
