[grpc] 1.68 Build on Windows produce huge lib files

[magnesj]

When building grpc 1.68 using default settings on Windows produce huge lib files. In the workflow we are using, the lib file is too big to fit into the cache for vcpkg on GitHub Actions. This causes very long build times, as grpc has to build from source on every run.

Here is a listing of file sizes compared to other libraries we build.

Proposed solution

Reduce file size on disk.

@magnesj, Thanks for your issue, The upstream should decide whether to delete so many lib files generated by grpc. I noticed that you have submitted an issue upstream. Let's track it in the issue grpc/grpc#38560.

Using dumpbin on Windows shows that there are large debug sections in grpc.lib the release build folder. I am using vcpkg.json and the triplet x64-windows-release

Here is our vcpkg.json https://github.com/OPM/ResInsight/blob/dev/vcpkg.json

Any hints on how to avoid debug symbols in release builds?
