[hat] Tensor - Matrix-Multiplication Example for GPUs

[jjfumero]

How to run?

We recommend running this example with the CUDA backend to be able to generate tensor instructions.

java @hat/run ffi-cuda tensors --iterations=100 --verbose --size=2048

OpenCL:

java @hat/run ffi-opencl tensors --iterations=100 --verbose --size=2048

This PR depends on the #998. Thus, we should merge that first before this one.

Since we rolled back the new API for tensors from the main branch, this PR can be closed without the merge. New tensor API development is still active and in progress in another branch:
