  Log Message:
  -----------
  [mlir][VectorOps] Adds canonicalization rewrite patterns for vector ShapeCastOp.

Summary:
Adds two rewrite patterns for the vector ShapeCastOp.
*) ShapeCastOp decomposer: decomposes ShapeCastOp on tuple-of-vectors to multiple ShapeCastOps each on vector types.
*) ShapeCastOp folder: folds canceling shape cast ops (e.g. shape_cast A -> B followed by shape_cast B -> A) away.
