feat(COMPONENT): Add Possibility to stop Page Change on Paginator

Feature Description

Currently when you press any button on the paginator the page is changed and the PageEvent is emitted afterwards.

It would be great to be able to intercept the pageEvent before it is done and maybe call something like event.stopPropagation() and or event.preventDefault()

Use Case

There is no way of stopping the page change for example if you would want to implement a dialog which confirms if the user wants to lose their changes made on the current page. (Especially when the paginator is not connected to the table and the pagination is used for the backend)
Here is a stackblitz that shows the problem.

首先在链接的 StackBlitz 中复现分页器的行为，并跟踪 PageEvent 相对于页面变化的发出时机。确定早期拦截应如何表示取消，然后验证已确认的导航仍会更改页面并按预期发出事件。
