  [mlir] Disallow broadcast dimensions on TransferWriteOp.

The current implementation allows for TransferWriteOps with broadcasts that do not make sense. E.g., a broadcast could write a vector into a single (scalar) memory location, which is effectively the same as writing only the last element of the vector.
