  Log Message:
  -----------
  [mlir][bufferization] Add tensor-like and buffer-like interfaces (#134220)

Current one-shot bufferization infrastructure operates on top of
TensorType and BaseMemRefType. These are non-extensible base classes of
the respective builtins: tensor and memref. Thus, the infrastructure is
bound to work only with builtin tensor/memref types. At the same time,
there are customization points that allow one to provide custom logic to
control the bufferization behavior.

This patch introduces new type interfaces: tensor-like and buffer-like
that aim to supersede TensorType/BaseMemRefType within the bufferization
dialect and allow custom tensors / memrefs to be used. Additionally,
these new type interfaces are attached to the respective builtin types
so that the switch is seamless.

Note that this patch does very minimal initial work, it does NOT
refactor bufferization infrastructure.
