[substrait] Build basic test suite to validate produced Substrait plans

### Is your feature request related to a problem or challenge?

In https://github.com/apache/datafusion/issues/12244 we found that DataFusion was producing invalid Substrait plans. The `datafusion-substrait` crate has quite a bit of tests but none that actually verify plans are valid according to the https://github.com/substrait-io/substrait-validator.

### Describe the solution you'd like

Add a test suite to the `datafusion-substrait` crate that uses https://github.com/substrait-io/substrait-validator to validate plans. We can start small and just add a test that would've failed prior to https://github.com/apache/datafusion/pull/15011.

### Describe alternatives you've considered

_No response_

### Additional context

_No response_

Start in the datafusion-substrait crate and review its existing tests, then inspect the substrait-validator and the invalid-plan context from issue 12244. Add a basic test that validates produced plans and would have caught the problem fixed by pull request 15011. Done means the test suite runs successfully and rejects invalid plans.
