Subject: [PATCH] Set up some DX features for OSS (#9565)

Summary:
These will be helpful both in the future and when applying parts of https://github.com/facebook/hhvm/issues/9564.

* Set up .editorconfig to ensure consistent indents.
* Instruct CMake to export a clangd JSON compilation database that IDEs can integrate with.
