Generate a standalone "zz_generated.terraformed.go" file for each res…

…ource

- Each resource will now have its own resource.Terraformed interface
  implementation file.
- The per-group "zz_generated_terraformed.go" is now split into
  per-resource "zz_generated.terraformed.go" files.
- This helps while generating multiple versions for the CRDs.
