feat: allow CustomType and RefType in arguments

[vaisshnavi7]

Description of changes: This PR allows the use of CustomType and RefType in arguments for custom operations in the @aws-amplify/data-schema package. Specifically:

1. Updated CustomOperation.ts to accept CustomType and RefType in CustomArguments.
2. Modified bridge-types.ts to include CustomType and RefType in relevant interfaces.
3. Added type tests in CustomOperations.test-d.ts to verify the new functionality.

These changes enhance the flexibility of schema definitions by allowing more complex argument structures in custom operations.

Testing:

• Added new type tests in CustomOperations.test-d.ts
• Manually verified using a test schema that correctly generates CustomType and RefType arguments

This PR is currently in draft because the unit test check failed. I'm investigating the issue and will update the PR once resolved.

Let's actually establish a feature branch and/or a branch for tagged releases instead of merging to main for now. I think this would leave main in a broken state (or at least an "odd" state) if the type changes are released ahead of the implementation changes. I.e., we'd be exposing a builder type that either fails or does nothing. And, I think in this case it would actually fail if these builder methods were called. Is that correct?

[vaisshnavi7]

Good point, @svidgen. I’ll set up a feature branch to keep main stable and ensure all builder methods align with the type changes. Appreciate the insight!
