Haojian Wu fdbe5b4b6f [clangd] Implement a smart version of HeaderSource switch.
Summary:
This patch implements another version header-source switch by incorporating the
AST and index, it will be used:
  - to improve the current header-source switch feature (layer with the
    existing file heuristic);
  - by the incoming define-outline code action;
