AVRO-3731 [java/gradle-plugin] retry on any schema parse failure

[steven-aerts]

With the introduction of the new SchemaParser in 1.12 the variety of errors which can be thrown when an unresolved type is found increased significantly. In the past unresolved type errors were tracked with a brittle regexp. In the newly proposed logic we propose to retry failed parse steps on any AvroRuntimeException. So this works for all past and future avro library versions.

@frevib this is a small proposal for an update on #3305 so the gradle plugin support 1.12 and others. Let me know what you think, and if I can help you improving it somehow.
