Help developers setup git-blame for Frameworks modules
See @ivan's comment from the clang-format tracking issue:
It would be cool to automatically do
git config --add blame.ignoreRevsFile .git-blame-ignore-revsif there's a.git-blame-ignore-revsfile in the repository - so that we can put clang-format commits to be automatically ignored when doinggit blame.
I imagine we'd want to gate this behind a config for users who are uncomfortable with any git-config manipulation but for the rest of us this seems it would improve the developer experience.
