This commit generalizes the special tensor.extract_slice/tensor.insert_slice bufferization rules to tensor subset ops. Ops that insert a tensor into a tensor at a specified subset (e.g., tensor.insert_slice, tensor.scatter) can implement the `SubsetInsertionOpInterface`. Apart from adding a new op interface (extending the API), this change is NFC. The only ops that currently implement the new interface are tensor.insert_slice and tensor.parallel_insert_slice, and those ops were are supported by One-Shot Bufferize.
