  -----------
  [mlir][Linalg] Add layout specification support to bufferization.

Previously, linalg bufferization always had to be conservative at function boundaries and assume the most dynamic strided memref layout.
This revision introduce the mechanism to specify a  linalg.buffer_layout function argument attribute that carries an affine map used to set a less pessimistic layout.
