Deep copy of (sub-)data structures

In addition to the shallow copy mechanism already provided by DenseMatrix, CSRMatrix, and Frame, there should also be a way to obtain a deep copy of an entire data object, or a part of it.

A DaphneIR operation for creating a deep copy of a data object was still missing, and I have just created it: CopyOp. Thus, this issue is about implementing a kernel for that operation. Here are a few thoughts:

• the input and output type can be assumed to be the same
• implementations would be useful for DenseMatrix, CSRMatrix, and Frame, or any subset of those
• if the input is a view into a larger data object, the output should be allocated with the size of the view, not the larger object
