[PATCH] D77392: [clangd] Make signatureHelp work with stale preambles

Herald added subscribers: cfe-commits, usaxena95, jfb, arphaman, mgrang, jkorous, MaskRay, javed.absar, ilya-biryukov.
Herald added a project: clang.

This is achieved by calculating newly added includes and implicitly
parsing them as if they were part of the main file.

This also gets rid of the need for consistent preamble reads.
