devel/git-filter-repo: import git-filter-repo-2.29.0

git filter-repo is a versatile tool for rewriting history. It roughly falls
into the same space of tool as git filter-branch but without the
capitulation-inducing poor performance, with far more capabilities, and with
a design that scales usability-wise beyond trivial rewriting cases.
git filter-repo is now recommended by the git project instead of
git filter-branch.
