[SPARK-15591][WEBUI] Paginate Stage Table in Stages tab

## What changes were proposed in this pull request?

This patch adds pagination support for the Stage Tables in the Stage tab. Pagination is provided for all of the four Job Tables (active, pending, completed, and failed). Besides, the paged stage tables are also used in JobPage (the detail page for one job) and PoolPage.

Interactions (jumping, sorting, and setting page size) for paged tables are also included.

## How was this patch tested?

Tested manually by using checking the Web UI after completing and failing hundreds of jobs.  Same as the testings for [Paginate Job Table in Jobs tab](https://github.com/apache/spark/pull/13620).

This shows the pagination for completed stages:
