clangd Integration #26
Description
Vendor the clangd/vscode-clangd codebase and tailor it for our needs:
- automatically find the correct compilation DB based on the active config
- restart
clangdon active config switch - change build command to dump the compilation DB on each run so that it's up-to-date
- make config file that uses Chromium's remote index when possible (unfortunately it doesn't support macOS/Windows)
- make config file that will background index Electron's codebase (small so should be fine) and defers indexing of Chromium code, ref https://linux.clangd-index.chromium.org/#user-content-will-clangd-still-know-about-my-local-changes
