chore(modules-sdk,orchestration): to remote joiner query (#4974)

Helper function to transform js/json object into RemoteJoinerQuery format.

```typescript
toRemoteJoinerQuery({
  product: {
    fields: ["id", "title"],
    __args: {
      skip: 0,
    },
    variants: {
      fields: ["id", "title", "handle", "sku"],
      shipping_profile: {
        profile: {
          fields: ["id", "name"],
        },
      },
    },
    collections: {
      fields: ["id", "title"],
    },
  },
})
```

outputs:
```
{
  alias: "product",
  fields: ["id", "title"],
  expands: [
    {
      property: "product.variants",
      fields: ["id", "title", "handle", "sku"],
    },
    {
      property: "product.variants.shipping_profile",
    },
    {
      property: "product.variants.shipping_profile.profile",
      fields: ["id", "name"],
    },
    {
      property: "product.collections",
      fields: ["id", "title"],
    },
  ],
  args: [
    {
      name: "skip",
      value: 0,
    },
  ],
};
```
