Packaging clangd with GRPC support

[Kirill Bobyrev]

Hi Sylvestre,

Thanks a lot for doing that!

I'm not sure if that would be directly what you want, but we have a bunch
of llvm-lit tests here:
https://github.com/llvm/llvm-project/tree/main/clang-tools-extra/clangd/test/remote-index

The main "helper" runs the index server and checks the output:
https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clangd/test/remote-index/pipeline_helper.py

However, that does require a clangd-index-server binary. Alternatively, I
think one can send some requests to the public LLVM Remote Index server (
https://clangd-index.llvm.org/) and have some verifications through that
(overall, we haven't observed any downtime so it's probably quite safe).

Thanks,
Kirill
