Generate schema from targets if present

[andrewhassan]

WHY are these changes introduced?

With target support, the generate schema command for functions no longer works.

Related issue: https://github.com/Shopify/script-service/issues/7327

WHAT is this pull request doing?

This PR uses a new GraphQL field to fetch the schema definition by target. The CLI uses the first target defined in a function to fetch the schema.

How to test your changes?

1. Create a function that uses targets
2. Run generate schema in the function directory
3. Ensure that the schema is fetched successfully

I don't think I need a changeset for this because it's a bug fix for existing functionality.

[nickwesselman]

We need this fix on 3.49 as well. Looks like @andrewhassan will be out today so I'll open another one.
