Subject: [PATCH] ci(windows): fix config codegen on Windows ARM64 (drop
 grpcio-tools)

The Windows build's "Install codegen tools" step ran `pip install grpcio-tools`,
whose grpcio C-extension has no Windows/ARM64 wheel for current Python and fails
to build from source on windows-11-arm, so protoc was unavailable and
run_codegen aborted at the compile step.

The codegen only needs a protoc binary + the protobuf runtime + pyyaml. Install
those directly on Windows instead: pip install protobuf (>=6.33.5, matching the
committed config_metadata_pb2.py runtime check) + pyyaml, and download a
standalone protoc (win64; runs under x64 emulation on arm64). run_codegen
prefers a standalone protoc on PATH, so grpcio-tools is no longer needed on
Windows. Linux/macOS steps keep grpcio-tools (wheels available there).

Verified locally: run_codegen with a protobuf-only venv (no grpcio-tools) +
standalone protoc 28.3 -> Lint passed (712 fields), Validation PASSED.
