Merge rov.2020.2 to master (#4522)

* Export symbols from onnx-import

* Fixed for cross-compilation

* Eliminate mismatch between opset1/opset2 and our real intentions (#4495)

* Removed operations from opset2 that were added to opset1 by mistake; added missing ops

* Fixed wrong include of opset1 to opset2

* Trigger CI

* Fixed code style

* CI triger
