[PATCH] D53399: [clangd] Ensure that we reply to each call exactly once. NFC (I think!)

================
Comment at: clangd/ClangdLSPServer.cpp:182
+  //  - if there were multiple replies, only the first is sent
+  class ReplyOnce {
+    struct State {
----------------
As discussed offline, we could potentially make this non-copyable to make harder to be duplicated and called more than once. And we could also get rid of the shared `State` in the functor.
