Generate a correct .flutter-plugin-dependencies file for iOS/macOS projects (flutter#162834)

Closes flutter#162704.

/cc @loic-sharma.

I expect I'll have to update some iOS/macOS unit and possibly
integration tests due to this change, but wanted something concrete to
talk about during our 1:1. Feel free to leave comments or questions even
if this PR is in "draft".
