* Specification for the NMS-4 operation (updated shape infer function) * Enabled NMS-4 in the Model Optimizer * Changed opset version for NMS with dynamic outputs and namespace to be "dynamic" * Added NMS-4 * Added opset4 to the nGraph * Added unit tests for NMS-4 type infer * Renamed UpgradeNMS3ToNMS4 to UpgradeNMS3ToNMSDynamic. Added stub for ConvertNMS4ToLegacy * Make IE aware of opset4 ops * Updated NMSIE to have different shape infer function based on the NMS it was converted from. Implemented NMS4->NMSIE conversion * Apply code style * Updated StaticShapeNonMaximumSuppression op in the VPU * Introduced new version of NMSIE operation with shape infer function from v4::NMS * Fixed dynamicToStaticNonMaxSuppression transformation * Added new version of NMSIE op with updated shape infer function * Fixed NMS4 to NMSIE2 transformation * Fixed constructors for nGraph ops v4::NM and dynamic::NMS * Updated text in the opset4 specification document * Code style fixes * Fixed constructors for StaticShapeNMS + fixed test * Minor change to the NMS op in the MO * Fixed typo in the dynamic_to_static_shape_non_max_suppression transformation * Removed redundant checks * Refactored NMS infer and validate functions * Added more checks to the validate_and_infer_types functions for NMS-3 and NMS-4 * Fixed compilation issue on Windows for op NMS * Code style fixes * Fixed typos in the NMSIE and NMSIE2 to CNNLayer op conversion * Fixed typo in the ie_cnn_layer_builder_ngraph.cpp * Fixed the NMSToLegacyNMS transformation. Added unit tests * Apply code review comments * Refactored NMSIE to use visitors * Removed calling ConvertNMS4ToLegacy in the common optimizations * Moved NMS4ToNMSLegacy to convert1_to_legacy group of transformations * Removed useless include statement * Removed copy-paste issue Co-authored-by: Evgeny Lazarev <elazarev.nnov@gmail.com>
