Anatoliy Talamanov 60848519b5 Merge pull request #23843 from TolyaTalamanov:at/fix-missing-opaque-kind-for-kernel G-API: Fix incorrect OpaqueKind for Kernel outputs #23843 ### Pull Request Readiness Checklist #### Overview The PR is going to fix several problems: 1. Major: `GKernel` doesn't hold `kind` for its outputs. Since `GModelBuilder` traverse graph from outputs to inputs once it reaches any output of the operation it will use its `kind` to create `Data` meta for all operation outputs. Since it essential for `python` to know `GTypeInfo` (which is `shape` and `kind`) it will be confused. Consider this operation: ``` @cv.gapi.op('custom.square_mean', in_types=[cv.GArray.Int], out_types=[cv.GOpaque.Float, cv.GArray.Int]) class GSquareMean: @staticmethod def outMeta(desc): return cv.empty_gopaque_desc(), cv.empty_array_desc() ``` Even though `GOpaque` is `Float`, corresponding metadata might have `Int` kind because it might be taken from `cv.GArray.Int` so it will be a problem if one of the outputs of these operation is graph output because python will cast it to the wrong type based on `Data` meta. 2. Minor: Some of the OpenVINO `IR`'s doesn't any layout information for input. It's usually true only for `IRv10` but since `OpenVINO 2.0` need this information to correctly configure resize we need to put default layout if there no such assigned in `ov::Model`.
