Release Notes: - Added switch source/header action for clangd language server (fixes [#12801](https://github.com/zed-industries/zed/issues/12801)). Note: I'm new to both rust and this codebase. I started my implementation by copying how rust analyzer's "expand macro" LSP extension is implemented. I don't yet understand some of the code I copied (mostly the way to get the `server_to_query` in `clangd_ext.rs` and the whole proto implementation). --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev>
