Summary:
In order for `CxxModule` modules to be able to do things like emit events, we need to expose the bridge instance.
To allow classes derived from `CxxModule` in other projects to include `<cxxreact/Instance.h> I also needed to convert all the header includes to non-relative ones.

Summary: Instead of sending a list of modules over to JS on startup (and actually blocking script execution) instead provide a proxy object that constructs each of these lazily.
