Feature Request: [Stats] On Posts list, set stat timeframe for which stats are displayed, and allow to sort based on stats count.

### Impacted plugin

Jetpack

### What

Add timeframe and sorting.

### How

As a user of a large WordPress site, I’d like to be able to identify which content hasn’t had any traffic. This will allow me to remove or update underperforming content.

- On the Posts screen in the WordPress admin, allow the user to define the timeframe for which stats are displayed.
- Allow the posts table to be sortable by the stats column.

Start with the Jetpack Stats integration on the WordPress admin Posts screen and trace how the existing stats column obtains and displays its values. Define the supported timeframe choices and the sorting behavior, then verify that users can identify posts with no traffic for the selected period.
