gRPC is currently getting formatted with two different clang-format implementations, and due to some weirdness they have different include file orderings. This change introduces clang-format configuration to ensure that the two systems align - it's *highly* expected that this will need some maintenance going forward as the two systems evolve. Closes #40905 PiperOrigin-RevId: 819606209
