This dependency makes clangd depend (transitively) on clangCodeGen, which it didn't depend on previously.

This makes clangd take ~30% longer to build, increases its binary size, and it's conceptually strange that a language server contains code generation code.

Any chance we could cut the dependency on clangCodeGen again?
