Matthias Springer 8143307b33 [mlir][bufferization] Generalize tensor slice rules to subset ops (#65619) ...

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.
