[ML][common] Add a method for cloning native tensors

ACR: TWDAPI-273/TWDAPI-274

This commit adds a method for cloning data and info from
ml_tensors_data_h and ml_tensors_info_h to TensorsData and related
TensorsInfo objects.

[Verification] Code compiles. Operation is verified in the next commit.
