[EPIC] Cross-testing coverage for Delete

[iwahbe]

What goes up must come down, even Pulumi programs.

Similar to #2537, we need comprehensive cross-tests for the Delete verb. We should have cross-tests for the same set of inputs that are used in the Create tests. Helpfully, those are already listed for Create.

Instead of writing separate tests for create and delete, we should write a single crosstest.CreateAndDelete case¹ (per library: SDKv2 and PF) and convert create tests described in #2537 to that function.

Footnotes

1. We can continue to expose crosstest.Create and expose crosstest.Delete, but they should be rarely used. ↩
