Add batch matrix-matrix product operation

## Description

Hello, there are a lot of functions from torch package not implemented (wrapped) in DJL.
For example batch matrix-matrix product operation: TORCH.BMM
It's looks like it should be wrapped in to NDArrays class.

May be there is some way i can dynamically create jni mapping for required function?
