  -----------
  [clangd] Add a textual fallback for go-to-definition

Summary:
This facilitates performing go-to-definition in contexts where AST-based
resolution does not work, such as comments, string literals, preprocessor
disabled regions, and macro definitions, based on textual lookup in the index.
