[mlir][linalg-transform] dyn_cast DestinationStyleOpInterface and early return (#166299 )

Use `dyn_cast` instead of `cast` and early return if op does not
implement the `DestinationStyleOpInterface`. Before the change the
following IR would cause a segfault when the transform interpreter is
run, where `myop.a` and `myop.b` implement the `TilingInterface` and not
the `DestinationStyleOpInterface`. Tried looking for ops in the upstream
dialect that implement the `TilingInterface` and not the
`DestinationStyleOpInterface` to add a test but could not find any.

```mlir
module {
func.func @fuse(%arg0: tensor<4x4x4xf32>, %arg1: tensor<4x4x4xf32>) -> tensor<4x4x4xf32> {
  %mul = "myop.a"(%arg0, %arg1) : (tensor<4x4x4xf32>, tensor<4x4x4xf32>) -> tensor<4x4x4xf32>
  %add = "myop.b"(%mul, %mul) : (tensor<4x4x4xf32>, tensor<4x4x4xf32>) -> tensor<4x4x4xf32>
  return %add : tensor<4x4x4xf32>
}

transform.sequence failures(propagate) {
^bb0(%func: !transform.any_op):
  %mul = transform.structured.match ops{["myop.a"]} in %func : (!transform.any_op) -> !transform.any_op
  %add = transform.structured.match ops{["myop.b"]} in %func : (!transform.any_op) -> !transform.any_op
  %loop, %tiled = transform.structured.tile_using_forall %add tile_sizes [1, 2, 4] : (!transform.any_op) -> (!transform.any_op, !transform.any_op)
  %mul_fused, %mul_containing = transform.structured.fuse_into_containing_op %mul into %tiled : (!transform.any_op, !transform.any_op) -> (!transform.any_op, !transform.any_op)
}
}
