Feat: Ability to reorder horizontally in ion-reorder

### Prerequisites

- [x] I have read the [Contributing Guidelines](https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#creating-an-issue).

- [x] I agree to follow the [Code of Conduct](https://ionicframework.com/code-of-conduct).

- [x] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already include this feature request, without success.

### Describe the Feature Request
It would be great to be able to reorder items horizontally, too. Now it is possible to do it only vertically

### Describe the Use Case
For example, being able to reorder photos in a photo gallery app. Reordering in y and x axis.

### Describe Preferred Solution
Implement `X` and `Y` axis reordering

### Describe Alternatives
No response

### Related Code
No response

### Additional Information
I know that this is double from [#29067](https://github.com/ionic-team/ionic-framework/issues/29067), but I have not found an answer whether it is possible to implement it now.
I'll attach my own design as an example.

首先定位 ion-reorder 组件，并了解其当前的垂直行为是如何定义的。确定水平或双轴重新排序的设计和验收标准；完成的实现应包括一个支持所述 X 轴和 Y 轴用例的可正常工作的实现。
