[mlir] Expose parseDimAndSymbolList from affineops.h

[stella.stamenova]

Summary

This was removed from ops.h, but it is used by onnx-mlir

mlir/include/mlir/Dialect/Affine/IR/AffineOps.h

 /// for all its uses in `region`.

+/// Parses dimension and symbol list and returns true if parsing failed.
