Print all duplicate types at once

[chao2zhang]

In our codebase, we have many duplicate types, queries and mutations. Printing all duplicates in one message could greatly reduce the turnaround time.

Tests

Manual as of now. Used multi-module-3 to verify the messages.

Before

* What went wrong:
Execution failed for task ':checkMultimodule3ApolloDuplicates'.
> duplicate Type 'ResolverKey(kind=OperationSelections, id=GetAnimal)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  Use 'alwaysGenerateTypesMatching' in a parent module to generate the type only once

After

* What went wrong:
Execution failed for task ':checkMultimodule3ApolloDuplicates'.
> duplicate Type 'ResolverKey(kind=OperationSelections, id=GetAnimal)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  duplicate Type 'ResolverKey(kind=ModelAdapter, id=operationData.GetAnimal.data.animal)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  duplicate Type 'ResolverKey(kind=ModelAdapter, id=operationData.GetAnimal.data)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  duplicate Type 'ResolverKey(kind=Operation, id=GetAnimal)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  duplicate Type 'ResolverKey(kind=Model, id=operationData.GetAnimal.data)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  duplicate Type 'ResolverKey(kind=Model, id=operationData.GetAnimal.data.animal)' generated in modules: :multi-module-3:child,:multi-module-3:child2
  Use 'alwaysGenerateTypesMatching' in a parent module to generate the type only once

Was the integration test flaky? I saw the check failed 1-2 hours ago and but now passed.

Was the integration test flaky?

Yup, happens sometimes. See #3920 for some of the gory details.

I relaunched it and it's all good now ✅ . Thanks for the contribution!
