[clang] [Windows] Add git-clang-format wrapper bat file (PR #69228)

[Chris B via cfe-commits]

https://github.com/llvm-beanz created https://github.com/llvm/llvm-project/pull/69228

This allows git-clang-format to be used on a Windows terminal without manually needing to find the path and invoke the python interpreter. We have a similar script for `scan-build`.
