Remove neuralnetworks HAL from frameworks/ml/nn/hardware/interfaces

The neuralnetworks hal was placed in
frameworks/ml/nn/hardware/interfaces while VTS tests were being
developed.

This CL removes it from frameworks/ml/nn/hardware/interfaces
and another CL moves it to hardware/interfaces.

VTS tests included in a sibling CL in this topic.
