First patch to enable diagnostic fix generation through modules. The
workflow will look like:

- ASTWorker letting modules know about diagnostics while building AST,

modules can read clang::Diagnostic and mutate clangd::Diagnostic through
that hook.

- Modules can implement and expose tweaks to fix diagnostics or act as

general refactorings.

- Tweak::Selection will contain information about the diagnostic

associated with the codeAction request to enable modules to fail their
diagnostic fixing tweakson prepare if need be.
