Matmul rework

The behavior of the reworked MatMul on the arguments in the following way.
- If both arguments are 2-D they are multiplied like conventional matrices.
- If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes.
Exp: For the MatMul of tensor A of shape (3,3,2) with tensor B of shape (3,2,4), A is a stack of three 2D matrices each of shape (3,2), and B is a stack of 3 2D matrices, each of shape (2,4).
