Add anomaly openvino task

[ashwinvaidya17]

Summary

• Add OpenVINO inference
• Should be merged after Fix the Anomaly Task to work & Add integration test for Anomaly #3007

How to test

task = OTXTaskType.ANOMALY_CLASSIFICATION
model = Padim(input_size=(256, 256), layers=["layer1", "layer2", "layer3"], backbone="resnet18")
transforms = [
    Resize(256, antialias=True),
    ToDtype(torch.float32, scale=True),
    Normalize(mean=(0.485, 0.456, 0.406), std=(0.229, 0.224, 0.225)),
]
datamodule = AnomalyDataModule(
            task_type=task,
            data_dir="/home/ashwin/datasets/MVTec/bottle",
            train_transforms=transforms,
            val_transforms=transforms,
            test_transforms=transforms,
        )
engine = Engine(
        datamodule=datamodule,
        task=task,
        model=model,
        val_check_interval=1.0,
        num_sanity_val_steps=0,
    )
engine.train(max_epochs=1)
engine.export(export_format=OTXExportFormatType.OPENVINO)
model = AnomalyOpenVINO(
    model_name="otx-workspace/exported_model.xml",
    async_inference=True,
    use_throughput_mode=False,
)

engine = Engine(
    model=model,
    datamodule=datamodule,
    task=task,
)
engine.test()
engine.predict()
