Create a build/bazel/product_config/generated/products/<product_name>/BUILD file that contains the platform definitions needed for a particular product. Currently we just create it for the current lunch target, but the idea is that eventually when all product config is in starlark, all the products will have their platform definitions in the tree at once.
