Recommit "[mlir][vector] Allow unroll of contraction in arbitrary order"

Fixed issue with vector.contract default unroll permutation.

Adds support for vector unroll transformations to unroll in different
orders. For example, the vector.contract can be unrolled into a
smaller set of contractions. There is a choice of how to unroll the
decomposition based on the traversal order of (dim0, dim1, dim2).
The choice of traversal order can now be specified by a callback which
given by the caller of the transform. For now, only the
vector.contract, vector.transfer_read/transfer_write operations
support the callback.
