  Log Message:
  -----------
  [mlir][vector] Add patterns to convert multidimreduce to vector.contract

add several patterns that will simplify contraction vectorization in the
future. With those canonicalizationns we will be able to remove the special
case for contration during vectorization and rely on those transformations to
avoid materizalizing broadcast ops.
