[Task]: Add OpenVINO Inference + Performance computation to Engine methods

[ashwinvaidya17]

What is the motivation for this task?

Currently, there is no way to compute the performance with OpenVINO models. Engine only accepts AnomlyModule for testing and prediction. It will be handy to have inference and metrics computation support for OpenVINO models as well.

Describe the solution you'd like

This might require some redesign on how we compute metrics. Ideally, we should be able to compute metrics on OpenVINO models as well.

Methods that require changing

class Engine:
    def predict(self, model: AnomalyModule | OVModel ...)
        ...

    def test(self, model: AnomalyModule | OVModel ...)
        ...
