[clangd] Add a callback mechanism for handling responses from client.
Summary:
The callback will be invoked in clangd when we receive a reply from the client.
This is a prerequisite of implementing a generic mechanism for chainable
refactorings (e.g. extract variable and rename), this would allow server to
trigger a new request to the LSP client after receiving a reply from the client.
