Automatically publish release packages to winget (#2445)

As of https://github.com/actions/runner-images/issues/12934, the Mac runners use CMake 4.0, which drops compatibility with CMake < 3.5, but the gRPC library version we use is marked as having CMake 3.1 as its minimum version.

Work around this by using `-DCMAKE_POLICY_VERSION_MINIMUM=3.5`.

 If possible, run with `--log=verbose` - note that the logs will include the contents of open files!
 If this is a crash, try to put `llvm-symbolizer` on your PATH per the troubleshooting instructions.
