Original issue's description:
> Fix missing GN dependencies.
>
> Fixes some cases where a dependency between a target's inputs and outputs exists without an explicit dependency.
>
> json_schema_api.gni was generating wrong names, this was fixed.
>
> mojo_application_package.gni was fixed to generate unique names (just a bug I noticed in passing) and support the testonly flag, which is necessary when I added the correct dependency.
>
> The rest of the cases are just adding deps or making existing deps public so that the ability to depend on the target's outputs is passed to dependents.
