[OpenVINO] Add Slice metatype

[kshpv]

Changes

Adds Slice operation - https://docs.openvino.ai/2022.3/openvino_docs_ops_movement_Slice_8.html
As a result the performance for modnet_webcam_portrait_matting from DLB was improved (local measurement)
from 44 FPS till 72 FPS.

Reason for changes

Fix incorrect quantization scheme due to unknown metatype

Don't we need to align nncf/common/hardware/configs/cpu.json and other schemes also?

I am not sure how to make this alignment. Could you clarify?

Our schemes from the nncf/common/hardware/configs are the basement for the quantization. Other NNCF parts (like metatypes) should be aligned with them, not vice-versa. For now, I don't see the Slice operation in nncf/common/hardware/configs/cpu.json.

Are there any models in our conformance run that contain Slice operation?

HWConfigOpName was added for Slice op and added to hw configs as well.

I did not check that, but all models passed

I did not check that, but all models passed

Why did you run this test then? What should it show?

To be sure that there is no regression on PTQ scope it was asked by other reviewer
