Packaging clangd with GRPC support

[Sam McCall]

Here's a patch against `snapshot` that works for me. (Unfortunately I can't
log into salsa - my account needs to be approved by someone).

It builds with GRPC support if the available version is acceptable (the one
I tested with - we've seen bugs with old library versions).
The resulting clangd packages have the right dependencies, and it doesn't
add any dependencies to clang/other packages.

The main problem is that due to Build-Depends if there's no grpc++-dev
package at all available (unusual arch or old distro?) then it will fail to
build entirely. Ideally we'd just build without remote index instead, but I
don't know the right way to set Build-Depends to achieve that.

What do I do next :-)
