  Log Message:
  -----------
  [mlir] [VectorOps] generalized vector.contract semantics

Summary:
Previously, vector.contract did not allow an empty set of
free or batch dimensions (K = 0) which defines a basic
reduction into a scalar (like a dot product). This CL
relaxes that restriction. Also adds constraints on
element type of operands and results. With tests.
