  -----------
  [mlir][tensors] Introduce attribute interface/attribute for tensor encoding

The new "encoding" field in tensor types so far had no meaning. This revision introduces:

1. an encoding attribute interface in IR: for verification between tensors and encodings in general
2. an attribute in Tensor dialect; #tensor.sparse<dict> + concrete sparse tensors API
