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.

route_guide_callback_client only works if started from the grpc/ directory. If started from other directories, it fails with the following error:
```
grpc/examples/cpp/route_guide
› ../../. /bazel-bin/examples/cpp/route_guide/route_guide_callback_client -db_path ./route_guide_db.json WARNING: All log messages before absl:: InitializeLog() is called are written to STDERR E0000 00:00:1740838254.946166 3533952 helper.cc:49] Failed to open examples/cpp/route_guide/route_guide_db.json

```
Add 'absl::ParseCommandLine(argc, argv)' to route_guide_callback_client so that the db_path argument is parsed.
